摘　　要：本文针对碘量法测定痕量次氯酸根（ＣｌＯ－）时，滴定中存在费时费试剂、痕量测定准确度欠佳的问题，研究并建立了流动注射化学发光法测定痕量ＣｌＯ－的新方法，具有较高的灵敏度、较好的准确度、重现性，为ＣｌＯ－的测定提供了一条新途径．该法在水质检验和环境监测中有一定的适用性．A new method is reported for the determination of trace amount of ClO-withacetone-H2O2-CLO-chemiluminescence system by FIA.The detection limit of the method is 4.9ng/ml for ClO-.If the range of CLO-concentration for the working curves was 3.0×10-8～3.0×10-ng/ml,the peak height was found to be linearly dependent on the concentration of CLO-.The relative standard deviation is less than 2.9%.The method was applied to determination ofClO- in water with satisfactory results.
