摘要
目的：探讨经前处理用比色法测定医院污水中总余氯的方法。方法：样品经沉淀处理进行比色分析。结果：方法检出限为0．02mg／L，相对标准偏差在1．36％~5．86％之间，加标回收率在95．0％~103％。结论：本法简便，快速，可用于医院污水中余氯的测定。
Objective： To discuss the measure of colorimetric determination of total residual chlorine in the hospital sewage through pretreatment. Methods： The samples that were precipitated and treated were analyzed colorimetrically. Results： The detection limit of the method was 0.02mg/L. The relative standard deviation was between 1.36%-5.86%.The spiked recoveries were between 95.0%~103.0%. Conclusion： The method is simple and fast that can be used for the determination oftotal residual chlorine in the hospital sewage.
