In the present study yeast biomass has been successfully used as biosorbent for removal of Crfrom aqueous solution. Yeasts of Saccharomyces cerevisiae are effective biosorbents for heavy metal ionsand it can be bought in large quantity at low cost. S. cerevisiae can remove toxic metals from aqueoussolutions to various levels. This low-cost biosorbent will make the process cost-effective and competitiveparticularly for environmental applications in detoxifying effluents. Langmuir’s and Freundlichs isothermswere also plotted to observe the maximum biosorption of heavy metal chromium (VI).

Aqueous Streams

The presence of toxic heavy metals such as chromium (VI) contaminants in aqueous streams, arising from the discharge of untreated metal containing effluents into water bodies, is one of the most important environmental problems. Adsorption is one of the effective techniques for chromium (VI) removal from wastewater. In the present study, adsorbent was prepared from low cost adsorbents and studies were carried out for chromium (VI) removal. Batch adsorption studies demonstrated that the adsorbents had significant capacity to adsorb the chromium from aqueous solution. It was found that the adsorption increased with increase in contact time and adsorbent dosage. An attempt was made to study mixed algae as an adsorbent for removal of chromium (VI).DOI: http://dx.doi.org/10.3126/on.v11i1.8238 Our Nature Vol.11(1) 2013: 11-16?

Removal of Cr(VI) from aqueous solution was studied using charred pomegranate fruit waste [CPW] as a new low cost biosorbent under batch method at room temperature. Its efficiency for removal of Cr(VI) was compared with raw pomegranate fruit waste[RPW]. Various sorption parameters such as contact time, initial concentration of Cr(VI) ion and effect of pH on the adsorption capacity of the biosorbent were studied. The adsorbent was effective for quantitative removal of Cr(VI) ions in highly acidic condition (pH=1) and equilibrium has been achieved in 2 hours. The adsorption isotherm data were fitted to Langmuir and Freundlich adsorption isotherm models and the model parameters were evaluated. Spectrophotometric method using diphenylcarbazide as a complexing reagent was used to analyze the chromium content in synthetic samples and the landfill site effluent collected from Kuleshwor, Kathmandu, Nepal.DOI: http://dx.doi.org/10.3126/jncs.v29i0.9256Journal of Nepal Chemical Society Vol. 29, 2012 Page:  81-88 Uploaded date: 12/5/2013
