Removal of Chromium (VI) from Synthetic Solution using dead Spirulina Species

Increasing industrialization in developing country like India leading difficulty in pollution control. One of the major causes of pollution in aquatic ecosystem is discharge of heavy metals. Wastewater containing heavy metals are treated with conventional technology like chemical precipitation, ion exchange etc. Biosorption of heavy metals from aqueous solution can be considered as an alternative technology in industrial wastewater treatment. This involves use of biomaterials like algae, fungi, bacteria, moss or waste coming from industrial operation and biological processes such as fermentation. This study was carried out to remove of Cr(VI) from aqueous solution by Spirulina Sp. In relating to this batch studies were conducted as function of a contact time, biosorbent dosage, pH and initial metal solution. The batch studies results showed the maximum removal efficiency of Cr(VI) as 83.6 %.
