The study of the EC process on the removal of iron, fluoride and arsenic from drinking water is an important step on the development of effective water treatment technologies for some world regions where the presence of those contaminants is a major health concern. Experimental results show that arsenic can be easily removed even in the presence of the other contaminants. Despite the slight reduction on the arsenic removal rate in the presence fluoride, the total removal can be achieved in less than 30 min of EC operation. On the other hand, the presence of iron presents a positive effect on the arsenic removal rate. Both fluoride and iron removal seem to benefit from each other presence in the EC operation. Moreover, the removal of both components is not significantly affected by the presence of arsenic. The simultaneous removal of the three pollutants can be achieved in less than 1 h of operation.

对某些饮用水中铁，氟和砷的EC处理方法的研究是开发有效水处理技术的重要一步，在某些世界地区，这些污染物的存在是一个主要的健康问题。实验结果表明，即使存在其他污染物，砷也可以轻松去除。尽管在存在氟化物的情况下砷的去除率略有降低，但总的去除可以在不到30分钟的EC操作中实现。另一方面，铁的存在对砷的去除率产生积极的影响。在EC操作中，除氟和除铁似乎都受益于彼此。而且，砷的存在对两种组分的去除没有显着影响。
