Abstract

Gonium sp. was tested for the bioremoval of Reactive Blue 220 (RB220) dye at different conditions such as pH values, initial dye concentrations and biomass concentrations to evaluate the possibility of using this microalga in treating wastewaters. According to the data obtained from the experiments, microalgae removed RB220 with the highest yield (54.2%) at pH 8, and could treat the applied dye with the highest removal percentage as 84.2% at the lowest dye concentration (26.2 mg/L RB220). Increasing Gonium sp. biomass concentration from 0.21 to 0.53 g/L stimulated RB220 removal rate from 87.7% to 96.8%. The present study clearly indicated that Gonium sp. biomass could be used as a bioremediation biosorbent in treating RB220 dye in the related wastewaters.
