Removal Of Contaminants

In the present study a consortium of four naturally isolated bacterial strains was evaluated as remediation tool for simultaneous removal ofphenol and Cr (VI) from tannery effluent. Application of bacterial consortia to effluent (pH 4.6) resulted in 100 and 78% removal of initial 47mg L-1 phenol and 16 mg L-1 Cr (VI), respectively at 96 h of treatment. The consortium was also active in removal of contaminants with lowerremoval rate in presence of extraneous higher concentrations of both phenol and Cr (VI). Treatment in static mode also resulted in removal ofpollutants, however with increase in agitation speed simultaneous reduction of contaminants becomes faster. Overall it can be inferred fromthe study that the above formulated bacterial consortium could effectively be used for treatment of phenol and Cr (VI) laden tannery and otherindustrial effluents.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11889   Int J Appl Sci Biotechnol, Vol. 3(1): 50-55

Non-radioactivestrontium(Sr2+) was used to investigate the migration of radioactivestrontium in loess. The sorption and retardation characteristics of strontiumin loess were studied by batch tests and column experiments. The experimentalresults showed that the equilibrium sorption data for Sr2+ was fitting well tothe Freundlich isotherm models(r2= 0.97). And the Rd obtained frombatch experiment was larger than Rd determined by column test. The resultsindicated that Rd values derived from column tests are more accurate toevaluate transport of radionuclides in contact medium.

Inhomogeneity Factor

The equilibrium sorption of uni-univalent electrolytes (NaCl, KCl) in heterogeneous cation exchange membranes with various contents of the ion exchange component and in ion exchange membranes Ralex was investigated. Using experimental data which express the concentration dependence of equilibrium sorption, validity of the Donnan relation for the systems under investigation was tested and values of the Glueckauf inhomogeneity factor for Ralex membranes were determined. Determination of the equilibrium sorption allows the effect of the total content of internal water and of the ion-exchange capacity on the distribution coefficients of the electrolyte to be determined.
