摘要:
自制高锰酸钾溶液、磷酸盐溶液和N,N-二乙基-1,4-苯二胺硫酸盐(DPD)溶液分别作为余氯标准液、缓冲液和显色剂,以分光光度法测试结果为余氯值标准,通过余氯仪检测饮用水中的余氯含量。比较传感器分别为隔膜式与恒电压型两种电化学在线余氯仪的测量结果,对检测中的主要影响因素氯胺进行研究。结果表明:水中无氯胺时,两种电化学法都能准确的测定水中余氯含量;存在氯胺时,恒电压型余氯仪的最大相对误差是隔膜式余氯仪的5倍。
Abstract:
Home-made potassium permanganate solution, phosphate solution and N, N- diethyl-1,4-phenylenediamine sulfate (DPD) solution were used as the residual chlorine standard liquid, buffer and chromogenic agent, respectively. Based on the spectrophotometry results, two electrochemical online chlorine analyzers, whose sensors are constant potential type and Clark type respectively, were compared through residual chlorine detection in running water. Besides, as an important factor, the influence of chloramine in the detection was investigated. All the results demonstrated that both electrochemical methods can determine the content of residual chlorine precisely in the absence of chloramine, but when the chloramine exists in the water, the maximum relative error of constant potential type is 5 times higher than that of Clark type.
