摘要：The effect of algae on the photoreduction of mercury (II) was investigated under the irradiation of metal halide lamps (ë ≥ 365 nm, 250W). Three algal species were used: Chlorella vulgarism, Anabaena cylindrical and Nitzschia hantzschiana. The enhancement effect was influenced by Fe(III) ions, humic substances, algal concentration, initial mercury (II) concentration and pH. The photoreduction rate of mercury (II) was found to increase with increasing the concentration of algae, pH, Fe (III) ions, and humic substances and decrease with increasing the concentration of initial mercury (II) concentration. The effects of different algae species on the photoreduction of Hg(II) followed the trend of Anabaena cylindrical > Nitzschia hantzschiana > Chlorella vulgarism under the same condition.
