摘要
利用氢氧化铁与砷化物共沉淀和吸附作用处理合砷废水．实验结果表明Ｆｅ３＋与Ａｓ３＋摩尔比为１０，ＰＨ值在９左右废水处理效果最好，废液中的砷含量在５．３×１０－３～４．７×１０３ｍｍｌ·Ｌ－１之间，低于容许排放标准．
Arsenium removal from wastewater was carried out, using iron sulphate with iron hydroxide as a coprecipitation agent in the basic condition.The results showed that in optimum conditions of Fe3+/As3+ molar ratio was equal to 10,at PH values around 9,while remaining arsenium concentration in the supernatant solution after filtration was found between 5. 3×1 0-3￣ 4.7× 10-3m.mol·L-1.
