Treatment of simulated Reactive Yellow 22 (Azo) dye effluents using Spirogryra species

摘要

The potential of commonly available green algae belonging to Spirogryra species was investigated as viable biomaterials for bio- loical treatment of simulated synthetic azo dye (Reactive yellow 22) effluents. The results obtained form the batch experiments revealed the ability of the algal species in removing the dye colour and was dependent both on the dye concentration and algal biomass. Maximum dye colour removal was observed on the third day for all the system conditions. Monitoring of ORP values helped to understand the overlying biochemical mechanism of algal-dye system.
