进行了小试研究，考察了水源水成分对三氯化铁和明矾混凝除砷效率的影响。检查的参数包括初始砷浓度和氧化状态、pH值以及共存无机溶质和天然有机物的存在。将基于表面络合模型的实验室实验和预测结果进行比较，以阐明砷去除机理，并确定控制砷去除效率的因素。

Bench-scale studies were conducted to examine the effects of source water composition on the efficiency of arsenic removal by coagulation with ferric chloride and alum. Parameters examined included initial arsenic concentrations and oxidation state, pH and the presence of co-occurring inorganic solutes and natural organic matter. The results of laboratory experiments and predictions based on surface complexation modeling are compared to elucidate the mechanisms of arsenic removal and to identify factors controlling arsenic removal efficiencies.
