摘要：

Study on the removal of Cr(VI) from aqueous solution using the S.cerevisiae as a biosorbent was carried out. The effects of various parameters such as contact time, sorbent dose, pH and initial concentrations were investigated, Cr(VI) removal is pH dependent and found to be maximum at pH 1. The experimental data fitted well to both Langmuir and Freundlich models. Pseudo-second-order model can well describe the kinetics process of Cr(VI) adsorption by S.cerevisiae. The results indicated that the S.cerevisiae is an efficient biosorbent for the removal of Cr(VI) from wastewater.
