Kinetic data presently obtained for iodination of xylidines in aqueous medium conclusively enlightened the order of the relative reactivities of xylidines in a quantitative manner. All the six reactions studied were found to be rapid, necessitating a special technique to follow the kinetics. The rotating platinum cathode method employed, yielded specific reaction rates that ranged from 52 to 893M-1s-1 and energies of activation from 32.7 to 54.5 kJ mol-1at 25.00C and 7 pH. Stereochemical principles invoked, justified this observed reactivity order for the isomers under study. Thus the subtleties of the stereochemistry of xylidines were quantitatively ascertained using kinetics as an investigational tool. <#LINE#> @ @ Pandey Bhawana and Fulekar M.H., Environmental Management- strategies for chemical disaster, Res.

Bioreactor performance is first simulated mathematically using PFDRs – in – series model that assumes the sludge bed and the sludge blanket each equivalent to a PFDR (plug flow dispersion reactor) but with different values of axial dispersion coefficient (D). Experimental values of DL are used in the computations. Alternate models that employ PFR – CSTR approach and the one proposed by Narayanan and Narayan are also considered for comparison. Dependence of total required height of reaction zone (L) with different system / operating parameters such as fractional conversion of substrate ) desired, feed concentration ( CS0 ) and feed flow rate have been studied separately. Computed values of design parameters are compared with experimental data collected from industrial units / pilot plants. It is observed that the sludge bed is not a tightly packed bed, but is a partially expanded bed. Axial dispersion and resistance to substrate transfer to sludge granules are significant and cannot be neglected. Among the different kinetic pathways analysed, data based on Andrews’ kinetic model that accommodates substrate inhibition to microbial growth agree more closely with experimental data. <#LINE#> @ @ Yu Liu and others, Mechanisms and Models for Anaerobic Granulation in UASB Reactors, Water Research, 37, 661 – 73 (2003) @No $ @ @ Kalyuzhnyi V.S. and Fedorovich, V.V., Dispersed Plug Flow Model for UASB Reactors with Focus on Granular Sludge Dynamics, J.

The objective of this work is to specially use only anion species to identify the facies present in the groundwater and the processes responsible for the modification of water chemistry in the area. 20 water samples were collected and analyzed using DR 2000 spectrophotometer and titrimetric method. The results indicated that pH range from 5.8 – 7.6 with an average of 6.5 while HCO, SO2- and Clreveal values ranging from 19.6 mg/l – 318.4 mg/l, 0.1 mg/l – 6.0 mg/l and 1.1 mg/l – 28.4 mg/l with mean values of 74.8 mg/l, 1.4 mg/l and 7.5 mg/l, respectively. CO2- was not detected in all the samples due to acidic to neutral pH condition. Based on the mean values, the anions were in the order of abundance as HCO� Cl� SO2-. The study identified Bicarbonate-Chloride-Sulphate facies as the only facies-type which is an indication of recently recharged groundwater with limited rock-water interaction. The plot of Cl/Cl + HCO against LogTDS revealed precipitation induced chemical weathering along with dissolution of rock forming minerals. <#LINE#> @ @ Amadi P.A. and Egboka B.C.E., The use of Anion Geochemistry I Mapping Groundwater in the Port Harcourt Area of the Niger Delta, Nigeria.

Characterization has been done on the basis of analytical conductance, magnetic data, infrared, electronic spectra , metal content analysis and HNMR data for the ligands. From analytical data the stoichiometry of the complexes has been found to be (1:1) (metal: ligand). IR spectra data suggest that the ligands behave as bidentate with N,N or S,S or S,S,N,N donor sequence toward the metal ions. On the basis of the above spectral, physicochemal, data as well as magnetic moment measurements tetrahedral and square planner geometries were assigned for the complexes. <#LINE#> @ @ Hyappa P.B., Young J.K., Moore J.S. and Suslic K.S.

Theoretically, the traditional remediation method is physical-chemical processes, which resulted in high capital cost and serious damage in contaminated sites. Currently, bioremediation is a developing biologic process that offers the possibility to destroy various contaminants using natural biological activity. Biopolymers are industrially attractive for a number of reasons; their capability of lowering transition metal-ion concentration to parts per billion concentrations, they are widely available and are environmentally safe.This paper deals with the preparation of protonated cross linked chitosan beads for the removal of chromium ions from aqueous solution. The effect of process parameters such as initial metal ion concentration, contact time, pH and temperature were studied on the performance of percentage removal of chromium. Adsorption isotherms and kinetic studies were established to test the solute interaction with solvent and rate of the reaction respectively. Thermodynamic parameters were also determined to find the nature and spontaneity of the reaction. <#LINE#> @ @ Aremu M.O., Gav B.L., Opaluwa O.D., Atolaiye B.O., Madu P.C. and Sangari D.U.

Vegetable wastes having near similar pH and moisture content have been chosen (carrot, beans and brinjal having pH 5.4, 5.8 and 5.7 respectively and moisture content 89.8%, 90.29% and 89.4% respectively) so that total solids content do not vary significantly in the feed composition for the study. These wastes contain predominantly carbohydrates and less protein and fat. The reactors were operated at two different organic loading rates (OLR) 0.25 and 0.5gVS/l.d, with the Hydraulic Retention Time (HRT) of 25days. The performance of the reactors was evaluated by estimating destruction of total and volatile Solids and by monitoring daily gas production. Volatile fatty acid (VFA) profile was determined for each organic load during the operation. The biogas yield was, 0.383 and 0.522 l/gTSadded and 0.423 and 0.576 l/gVSadded for the two OLR respectively. The methane content in the gas was around 63% and methane yield was 0.226 and 0.362 l CH / gVSadded for the selected vegetables for the two OLR respectively. The objective of this paper was to study the effective conversion of carbohydrate content in the selected mixture of vegetable wastes in a single stage anaerobic reactor for biogas production. <#LINE#> @ @ Gunaselan N.V., Anaerobic digestion of biomass for methane production: a review, Biomass and Bioenergy,13 , 83 – 11(1997) @No $ @ @ Nirmala B., Deepak S and Sunil K., Biomethanation of Banana peel and Pineapple waste, Bioresource Technology, 58, 73-76 (1996) @No $ @ @ Bouallagui H., BenCheikh R., Marouani L. and Hamdi M., Mesophilic biogas production from fruit and vegetable waste in tubular digester, Bioresour Technol, 86, 85-90 (2003) @No $ @ @ Mata.

Two groups of bed sediments samples were collected from three sites during February 2008 and June 2008. The samples were analyzed to determine their heavy metals (Cd, Pb, Ni, Zn, Cu, Fe and Cr), pH and Total organic carbon (TOC %) content. The results showed that the heavy metal concentrations were slightly higher in February than those sampled in June. The results also showed that metal content are directly correlated to TOC%. Environmental assessment of sediments pollution by heavy metal was carried out using geo-accumulation index (Igeo) and comparison with Canadian, Dutch and German targets for sediment quality Guidelines. The results indicated that natural processes such as weathering and erosion of bedrock are the main supply sources of heavy metals in sediments of Otamiri Rivers near Owerri, as the sediments were noted to be in unpolluted or excellent state. <#LINE#> @ @ Sheikh M.A., Noah N.M., Tsuha K. and Oomoti T., Occurrence of tributyltin compounds and characteristics of heavy metals, Int.

Composites were fabricated using compression moulding technique.The results demonstrate that hybridization play an important role for improving the mechanical properties of composites. The tensile and flexural properties of hybrid composites are markedly improved as compare to unhybrid composites. Water Sorptionbehaviour of composite was also studied. Water absorption behaviour indicated that hybrid composites offer better resistance to water absorption. This work demonstrates the potential of thehybrid natural fibre composite materials for use in a number of consumable goods. <#LINE#> @ @ Santulli C., Impact properties of glass/plant fibre hybrid laminates, J Mater Sci, 42, 3699–3707, (2007) @No $ @ @ Albuquerque A.C., Joseph K., de Carvalho L.H. and de Almeida J.
