© 2018, Islamic Azad University (IAU). The increasing discharge of wastewater with chromium(VI) plays adverse impacts on the environment in recent years. This study purposes to investigate the adsorption efficiency and removal mechanism of chromium(VI) via a purified indigenous bacteria (Leifsonia sp.). The effect of varying pH, initial chromium(VI) concentration, dosage of dry biosorbent, contact time and temperature on the adsorption efficiency of chromium(VI) was studied via single-factor experiment. Our results demonstrate that the strain has high efficiency of adsorbing chromium(VI) from aqueous solution. The maximum removal rate of chromium(VI) was 95.4% when pH was 2 (range 1.5–9.0), ..View full abstract
