摘要
A(sⅢ)的毒性是A(sⅤ)的60倍,而且比A(sⅤ)更难去除,已经受到越来越多的关注。文章从As(Ⅲ)的氧化动力学、常用混凝剂的除砷效果和氧化-混凝法对As(Ⅲ)的去除三个方面介绍了国内外在除As(Ⅲ)领域的研究进展,详细阐述了各种方法的优缺点,并对未来的研究方向进行了展望。
Since As(Ⅲ)is more toxic than As(Ⅴ)and more difficult to be removed,As(Ⅲ)removal from drinking water is attracting more and more attentions.Progress on oxidation kinetics of As(Ⅲ),removal efficiency by traditional coagulants and removal by oxidation and subsequent coagulation was discussed,with comparison of the merits and disadvantaged of each method.The future study in A(sⅢ)removal was also proposed.
