<#LINE#>Extraction of Phenol from Industrial Water Using Different Solvents<#LINE#>Jabrou@SallyN.<#LINE#>1-12<#LINE#>1.ISCA-RJCS-2012-001 Done.pdf<#LINE#> Department of Radiology, Health and Medical Technical College Foundation of Technical Education, Baghdad, IRAQ  <#LINE#>9/1/2012<#LINE#>18/1/2012<#LINE#>The analysis and efficiency of phenol extraction from the industrial water using different solvents, were investigated. To our knowledge, the experimental information available in the literature for liquid-liquid equilibria of ternary mixtures containing the pair phenol-water is limited. Therefore the purpose of the present investigation is to generate the data for the water-phenol with different solvents to aid the correlation of liquid-liquid equilibria, including phase diagrams, distribution coefficients of phenol, tie-lines data and selectivity of the solvents for the aqueous phenol system. The ternary equilibrium diagrams and tie-lines data for systems containing Water-Phenol-Benzene, Water-Phenol-Chloroform, Water-Phenol-iso-Butyl Acetate, Water-Phenol-Butanol, Water-Phenol-Ethyl Methyl Keton and Water-Phenol-Toluene, were determined at 303 K and atmospheric pressure. The capacity and selectivity of these organic solvents in each of these systems were determined from the tie-lines data. The capacity of the isobutyle acetate was found to be the highest among the other solvents, and its selectivity was also the highest. Similar results also were obtained for the ethyl methyl keton but gave less capacity and selectivity as compared to the isobutyle acetate. It can be concluded that both isobutyle acetate and ethyl methyl keton are good solvents for extraction of phenol from industrial water. The liquid-liquid equilibrium data of ternary systems were correlated to the NRTL, UNIQUAC and UNIFAC models of activity coefficient to determine their adjustable parameters. The standard deviations from experimental compositions were calculated. Results show that the correlation may be greatly improved by applying the NRTL model with the regression criteria based on minimizing the experimental and calculating distribution coefficients SK to give an average value of the root mean square deviation about 1.436 % and in terms of the average errors in the distribution ratio for all tie-lines about 10.776%.<#LINE#> @ @  Alders L., Liquid-Liquid Extraction, 2nd ed., Elsevier publishing Co., (1959) @No $ @ @  Anderson T.F. and Prausnitz J.M., Ind.

This investigation studies the use of a non-useful plant material as naturally occurring biosorbents for the removal of cationic pollutants in wastewater. The effect of pH on the sorption of Al3+ and Cr6+ ion unto Terminalia catappa biomass was investigated. The experimental results have been analysed in terms of Langmuir and Freundlich isotherms. The data showed that the maximum pH (pH max) for efficient sorption of Al3+ was 4.0 (85.5 mg/g) and for Cr6+ 2.0 (82.6 mg/g). Evaluation using Langmuir equation gave the monolayer sorption capacity as 1.12mg/g and 2.67mg/g at the respective pHmax for Al3+ and Cr6+. The thermodynamic assessment of the metal ion – Terminalia catappa L. biomass system indicates the feasibility and spontaneous nature of the process.  <#LINE#> @ @ Vinod V.P. and Antrudhan T.S., Sorption of Tanic acid on zirconium pillared clay, J.

<#LINE#>Corrosion Protection of Zinc in Natural Sea Water using Citrullus Vulgaris peel  as an Inhibitor<#LINE#>A.@Petchiammal,P.@DeepaRani,S.@Selvaraj,K.@Kalirajan<#LINE#>24-34<#LINE#>4.ISCA-RJCS-2012-017 Done.pdf<#LINE#> PG and Research Department of Chemistry, Sri Paramakalyani College, Alwarkurichi-627412, Tamil Nadu, India  <#LINE#>31/1/2012<#LINE#>6/2/2012<#LINE#> The effect of Citrullus Vulgaris peel on the corrosion of zinc in natural sea water has been studied by mass loss measurements at different time and temperature. The present investigation revealed that the percentage of inhibition efficiency is increased with increase of inhibitor concentration and decreased with rise in period of contact. The temperature studies reflect that the percentage of inhibition efficiency is decreased with increase of temperature and it indicates that the mechanism of  physical adsorption. The calculated values of activation energy (Ea) also support the physisorption process. The thermodynamic parameters such as heat of adsorption (Qads) and free energy of adsorption (∆G ads) are suggested that the adsorption of inhibitor on the zinc metal surface is exothermic and followed by spontaneous process.   Experimental data has fitted with the Langmuir and Temkin adsorption isotherm. The corrosion products on the metal surface in the presence and absence of inhibitor is analysed by FTIR and XRD studies. The rich of main compounds namely zinc oxide (ZnO) and Pottasium diaquatrichlorozincate(II) (K [ZnCl3(H 2O)2]) are formed on the metal surface  may be confirmed by XRD spectrum. The observed results concluded that the Citrullus Vulgaris peel could serve as an effective inhibitor on zinc in natural sea water environment.  <#LINE#> @ @  US Report on Corrosion Costs and Preventive Strategies in the United States, www.corrosioncost.com, July (2002) @No $ @ @  Popoola A.P.I. and Fayomi O.S.I., Electrochemical Study of Zinc Plate in Acid Medium, Inhibitory Effect of Bitter Leaf (Vernonia Amygdalina), Int.

These are present in the urban atmosphere in both exhaust and evaporative emissions from vehicles and fuel delivery outlets. The present paper gives an account of BTX levels in urban environment of Delhi measured since May 2008 to April 2010. Active sampling technique has been employed for measurements. A significant decrease (from 17.05/58.98/15.45 �g/m3 to 16.00/52.99/14.22 �g/m3 for B/T/X respectively during 2008-2009 and 2009-2010) was observed in the levels in the initial stage but the levels were found higher than the limiting value prescribed by CPCB (i.e. 5 �g/m3- annual average for benzene). This indicates that in the urban atmosphere BTX do not dissipate easily in the environment and therefore, needs serious thought for reduction.  <#LINE#> @ @  Central Pollution Control Board (CPCB), Monitoring of benzene level in ambient air of Delhi, CPCB Report TOS-1(1999-2000) @No $ @ @ Tyagi S.K., BTX profile of fugitive emission and ambient air at Panipat refinery, Ind.

These values have been used to calculate the excess molar volume (VE) and the viscosity deviations (Δη) and Grunberg – Nissan interaction constant (d') of the binary mixtures. The viscosity values were fitted to the models of McAllister, Krishnan-Laddha, Jouyban – Acree model. The excess values were correlated using the Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. It was found that in all cases the experimental data obtained fitted with the values correlated by the corresponding model very well. The molecular interactions existing between the components were also discussed.  <#LINE#> @ @  Ewing  M.B.

The samples have been characterized by SEM(scanning electron microscopy) which reveal the size of the nano particles as 50-100nm. These studies infer that the particles are spherical in shape. The UV-Vis spectra show that an absorption peak, occurring due to Surface Plasmon Resonance (SPR), exists at 420.226nm. Silver nano particles were prepared. Silver nano particles are used as a catalyst for the photocatalytic degradation of acid green 3GM and Blue ffs acid in the presence of H2O2. The kinetic study reveals that the photo catalytic degradation process is faster in the presence of silver nano particles/H2O2.  <#LINE#> @ @   Robinson T., McMullan G., Marchant R. and Nigam, Bioresour.

In this study we determined the concentrations of these elemental impurities in twenty-eight different brands of paediatric syrups, purchased randomly from patent medicine retail outlets in Port Harcourt, Rivers State, Nigeria. The aim of this study is to compare the antimony, tin and mercury levels in these paediatric syrups with the recommended limits United States Pharmacopea USP. Twenty eight different paediatric syrups were randomly sampled and purchased using the market basket protocol  from pharmacy shops in Port Harcourt city, Rivers State, Nigeria in December 2010. Syrups were ashed before digestion using conc. aqua regia, HCl: HNO3 (3:1) and chromium and cobalt were analysed using Unicam Atomic Absorption Spectrophotometer (AAS) Model 929. The range of heavy metal content in these paediatric syrups were 0.66�g/g – 2.04�g/g and 0.62�g/g – 2.02�g/g for chromium and cobalt respectively. The mean of chromium and cobalt in these paediatric syrups were 1.571�0.069 and 1.015�0.0083 respectively. The estimation of chromium and cobalt as a result of the consumption of paediatric syrups on an average daily basis were 29.35�g/g and 29.9�g/g respectively. Chromium and cobalt content in paediatric syrups did not constitute a significant source of heavy metal exposure to the children.<#LINE#> @ @  Roy J., Pharmaceutical Impurities- A Mini-Review, AAPS Pharm Sci Tech., 3(2), (2002) @No $ @ @  Oberg T. and Bergstrom J., Chromium as a potential catalyst in the thermal formation of chlorinated aromatic compounds, Organohalogen compounds 66 (2004) @No $ @ @  Mertz W., Chromium and its relation to carbohydrate metabolism, Med.

The extended solvation model provides more insights into this interaction for further understanding of the effect of iso-propyl and iso-butyl xanthate on the stability and the structural changes of MT. The solvation parameters derived from the solvation model can be related to the changes in the stability of enzyme and type of inhibition. ITC implies that there is a set of two binding sites for two new synthesized xanthates on MT with non cooperativity in the binding process.  <#LINE#> @ @  Rescigno A., Sollai F., Pisu B., Rinaldi A., and Sanjust E.

Simulations on mathematical models has several advantages over the experiment on a real model or system. The mathematical model is developed from material balances. Simulation is very important and popular tool now a days, when computation speed of computers increases exponentially every day numerical mathematics is used for steady-state analysis and dynamic analysis. Simulation results are used for choosing of an optimal working point and an external linear model of this nonlinear plant. This paper deals with simulation experiments on one type of nonlinear systems, CSTR reactor. This simulations results in optimal working point, external linear model and they will be later used for choosing of an optimal working point and mainly for control purpose.  <#LINE#> @ @  Ingham J., Dunn I.J., Heinzle E. and Prenosil J.E., Chemical Engineering Dynamics.
