Effect of chloride addition on arsenite removal by electrocoagulation process was carried out in this study. Electrocoagulation experiments were executed in a 5 L capacity rectangular tank equipped with 7 anodes and 7 cathodes. Addition of chloride significantly enhanced the arsenite removal efficiency of electrocoagulation process and the removal is purely by the separation process, rather than the oxidation of arsenite to arsenate by electrolytically generated active chlorine. 250 mg L⁻¹ of chloride was found as optimal, and more than 99 % of arsenite were removed from its initial concentration of 1 mg L⁻¹ at pH 6, applied voltage of 5 V, and 60 min of electrolysis. Sludge produced after electrocoagulation treatment was analyzed by scanning electron microscopy (SEM) / energy dispersive X‐ray analysis (EDAX), X‐ray diffraction (XRD), and Fourier transforms infrared (FTIR) techniques.

添加氯化物对铝电凝去除砷的重要性

在这项研究中进行了氯化物添加对通过电凝过程去除亚砷酸盐的影响。电凝实验是在装有7个阳极和7个阴极的5升容量矩形槽中进行的。氯化物的添加显着提高了电凝过程中砷的去除效率，并且去除完全是通过分离过程进行的，而不是通过电解生成的活性氯将砷氧化为砷。发现最佳的氯化物是250 mg L ^-1，并且从其初始浓度1 mg L ^-1中除去了99％以上的亚砷酸盐。在pH值为6时，施加5 V电压，并电解60分钟。电凝处理后产生的污泥通过扫描电子显微镜（SEM）/能量色散X射线分析（EDAX），X射线衍射（XRD）和傅里叶变换红外（FTIR）技术进行分析。
