摘　　要：针对现行《循环水分析和试验方法》中循环水总铁测定方法中存在的问题进行了改进,提出了新的测定方法。试验结果表明,新方法简单快速,反应完全,稳定性好,其相对标准偏差小于2%,加标回收率为98%～102%,适用于生产实际。An improvement has been made with a new determination method proposed in view of the existing questions with the method to determine the total iron in circulating water in the current Method for Analysis and Test of Circulating Water. The results of tests showed that the new method was simple and quick, with which the reaction was complete, the stability was good, the relative standard deviation was smaller than 2%, and the standard sample-added recovery rate was 98%~102%, which indicates that this method is applicable to actual production.
