不含铁的

The most common methods of removing arsenic from aqueous process streams are by precipitation as arsenic sulfide, calcium arsenate, or ferric arsenate, but it has been suitable for direct disposal to uncontained sites as they will produce leachate containing arsenic.

从水中去除砷是最常用的做法，工艺流程是通过沉淀类似硫化砷、砷酸钙或者砷酸铁，由于会产生含砷的沥出夜，因此这种方法适合用于不限制排放场所的直接处置。
