REMOVAL OF HEXAVALENT CHROMIUM AND OTHER METAL IONS USING SPIROGYRA AEQUETIALIS: AS LOW-COST ADSORBENT

Pandhare R. S., S. G. Gupta

Abstract


The metals in high concentration are always toxic to living organisms. The industrial development is increasing the problem of heavy metal pollution. Each day new chemicals are introduced to environment. Manifestations of heavy metals on humans can vary from sub-clinical forms not directly attributed to heavy metal pollution like lowering IQ of children exposed to chronic lead poisoning to bloody diarrhoea and suppression of urine formation from ingestion of corrosive mercury. Biosorption is an innovative technology that employs inactive and dead biomass for the recovery of heavy metals from aqueous solutions. As an alternative to traditional methods its promising results are now being considered for application by the scientific community. In the recent work is focused on studies on the biosorption of Cr (VI) by dry biomass    of Spirogyra and further used for growth independent sorption of Cr (VI). Various parameter influencing the biosorption of Cr (VI) were also studied.
