<#LINE#>Chemical Partitioning of Iron, Cadmium, Nickel and Chromium in Contaminated Soils of South-Eastern Nigeria<#LINE#>S.A.@Osakwe<#LINE#>1-9<#LINE#>1.ISCA-RJCS-2012-008_Done.pdf<#LINE#> Department of Chemistry, Delta State University, Abraka, NIGERIA  <#LINE#>20/1/2012<#LINE#>30/1/2012<#LINE#> Selected heavy metals Fe, Cd, Ni, and Cr were studied in contaminated soil samples collected from South – Eastern Nigeria, for their geochemical differentiation into different chemical fractions, using Ma and Rao six steps sequential chemical extraction procedure in order to assess the potential mobility and bioavailability of the heavy metals in the soil profiles. It is evident from the study that the residual fraction was the most important phase for the four heavy metals under study with the following average percentage values 74.43 for Fe, 37.69 for Cd, 70.11for Ni and 62.47 for Cr. The carbonate fraction contained an appreciable portion of Fe, Cd and Ni with the average percentage values of 16.29, 14.86 and 10.47 respectively, while organic fraction was of next importance for Cr with an average percentage value of 27.14. Fe – Mn oxide fraction also contained 15.86% of Cd. Relatively low amount of the metals were associated with water soluble and exchangeable fractions. The mobility factors for the metals in all the sites ranged from 8.55 to 40.04 for Fe, 8.66 to 56.58 for Cd, 12.74 to 30.19 for Ni and 0.82 to 7.22 for Cr. The generally low values of mobility factors coupled with significantly high level of association of the metals with the residual fraction, indicate that the metals do not pose any environmental risk or hazard.  <#LINE#> @ @  Sadiq M.

As water is an integral part of this system, corrosion among the piping is inevitable. Corrosion tends to disintegrate the piping substance making it fragile and easy to rupture. The disintegrated parts of the piping could block the system and cause a decline in pressure and contributes to water pollution. Essentially, industries use inhibitor to retard corrosion and generally there are toxic and exhibit carcinogenic properties. However, these vital inhibitors are still being used in a small quantity due to lack of safe, natural based corrosion inhibitor. Accordingly, the current study describes the potential of using Allium cepa (Onion) as a natural corrosion inhibitor. The effectiveness of using Allium cepa was characterized in terms of metal weight loss, inhibitory efficiency, corrosion rate, area affected, turbidity and pH. Results showed that the optimum inhibition efficiency (IE) for iron, nickel and copper were 92%, 88% and 46%, respectively when Allium cepa was present at 0.6 g/L. In addition, the reduction in weight loss for iron, nickel and copper were 92%, 88% and 46%, respectively, demonstrating Allium cepa as an effective corrosion inhibitor, primarily for iron.  <#LINE#> @ @  Bouyanzer A., Hammouti B. and Majidi L., Pennyroyal oil from Mentha pulegium as corrosion inhibitor for steel in 1 M HCL, J.

The resources of fossil fuel in Lithuania are very limited. Since fossil fuel resources are rapidly diminishing, there is a global focus on renewable energy sources and developing new energy-saving technologies. The use of energy sources such as sapropel (sludge lakes), not only require less imported fossil fuels, but also dealt with a very topical issue of environmental pollution. It was found that the use of briquettes consisting of sapropel can help save other energy resources. The combustion process of such briquettes is longer than conventional briquettes as sapropel samples reduce shrinkage and intensify the combustion process. Because of its good physical and chemical properties sapropel can be mixed with other types of biofuels such as straw, sawdust or peat. This study has found the calorific value of sapropel and its mixtures and the measured concentrations of gaseous pollutants sapropel briquettes during combustion. Manufactured briquettes (sapropel - straw, sapropel – peat, sapropel - sawdust) were combusted in a residential boiler and in the combustion process the concentrations of gaseous pollutants were measured. It was determined that the sapropel and biofuel addictives briquettes can be burned, and the concentration of pollutants at the combustion process does not exceed the normative limits.  <#LINE#> @ @  Gimbutaitė I. and Venckus Z., Air Pollution Burning Different Kinds of Wood in Small Power Boilers, J.

College of Technology, Anna University, Chennai, 600 025 INDIA   <#LINE#>2/3/2012<#LINE#>6/3/2012<#LINE#>A broad research of the solubility and mass transfer coefficient enhancement of triphenylcarbinole through hydrotropy has been commenced. The solubility investigations have been carried out with hydrotropes such as potassium acetate, sodium saccharin, and sodium toluene sulfonate, for a wide concentration range from 0 to 3.0 mol/L along with system temperature from 303K to 333 K. The effectiveness of hydrotropes was measured by the determination of Setschenow constant “Ks”. The solubility of triphenylcarbinole increases with increasing hydrotrope concentration and also with system temperature. A minimum hydrotrope concentration (MHC) in the aqueous phase was required to initiate significant solubilization of triphenylcarbinole. Consequent to the increase in solubilization of triphenylcarbinole, the mass transfer coefficient was also found to increase with increasing hydrotrope concentration. A threshold value of MHC is to be maintained to have an appreciable enhancement in the mass transfer coefficient. The maximum enhancement factor, which is the ratio of the solubility values in the presence and absence of a hydrotrope, has been determined for all sets of experiments.  <#LINE#> @ @  Neuberg C., Hydrotropy, Biochem.

It was shown that the composition of the catalyst, which is formed at the pretreatment stage, changes with the increase of H2 content in the reaction mixture. According to PXRD data the catalyst formed contains two phases: CuO and Cu2(OH)3NO3, except that formed in the reaction mixture with excess of H2 and deficiency of O2, which contains three phases and possesses the lowest catalytic activity. Total CO conversion has been reached at 438 K and the selectivity towards CO oxidation was 94 % at this temperature. However, the composite catalyst has been found to be active and high selective only in the reaction mixture with a small excess of H2. The selectivity towards CO oxidation has been sharply decreased with increase of H2 content in the reaction mixture. The average particle size for composite catalyst studied was found to be about 20 nm. The increase of H2 content in the reaction mixture did not much change the crystallite size of the composite catalyst components.   <#LINE#> @ @  Sonawane V.Y., Mechanistic study of chromium (VI) catalyzed oxidation of benzyl alcohol by polymer supported chromic acid, Res.

But a large amount of tree borne oils and fats are available for biodiesel production in developing and under develop countries. Simarouba glauca oil is one of these oils. This paper deals with the transesterification of Simarouba glauca oil by means of methanol in presence of Potassium hydroxide catalyst at less than 650C. The viscosity of biodiesel is nearer to that of the diesel. The biodiesel is characterized by TLC and the important properties of biodiesel such as density, flash point, cloud point, pour point, carbon residue and ash content are found out and compared with that of diesel. The studies encourage the production of biodiesel from unrefined Simarouba glauca oil as viable alternative to the diesel fuel.  <#LINE#> @ @  Gilman E.F. and Watson D.G., Simarouba glauca: Paradise-Tree, Institute of Food and Agricultural Sciences, University of Florida, Gainesville FL 32611.

The aim of the investigation was to measure the influence of chromium (III) on urease activity. Urease activity in pure solution was so sensitive for Cr (III), which caused inhibition of urease activity significantly. The complexation between Cr3+ and Jack bean urease is examined using isothermal titration calorimetry (ITC). It was found that chromium ions acted as a noncooperative inhibitor of JBU, and there is a set of 12 identical and independent binding sites for Cr3+ ions. The association equilibrium constant is 6.79�106 L-1.mol, indicating the strong interaction of Cr3+ ion with JBU.  The molar enthalpy of binding is DH = 15.10 kJmol-1.  <#LINE#> @ @  Vicario L.R.

This paper describe and present the results of experiments in exposure chamber to determine the effects of different ambient air temperature (T) and relatively humidity (RH) on the performances of passive diffusive samplers for measuring nitrogen dioxide (NO2) in the outdoor environment. In experimental studies were used passive diffusive samplers with stainless steel grids and impregnating solution of 10% (v/v) triethanolamine (TEA) with water. During these researches in laboratory chamber passive samplers was exposed at various conditions: temperature from 10�C to 40�C and relatively humidity from 30% to 80%. During these variations in conditions NO2 concentration was constant, approximately 40 μg/m3. Influence of temperature and relative humidity are weak on passive sampler performance when ambient temperature is 20�C and relatively humidity 60%. Changing environmental conditions (T &#65533; 30 �C and RH &#65533; 75 %) indicates accuracy of passive samplers 10–35% when compared to co-located continuous NOx analyzer.   <#LINE#> @ @  Heal M.R., O’Donoghue M.A., Agius R.M. and Beverland I.
