목적：탐토경전처리용비색법측정의원오수중총여록적방법。방법：양품경침정처리진행비색분석。결과：방법검출한위0.02 mg/L，상대표준편차재1.36%~5.86%지간，가표회수솔재95.0%~103%。결론：본법간편，쾌속，가용우의원오수중여록적측정。
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 of total residual chlorine in the hospital sewage.
