摘　　要：本文采用德国SEALAA3 HR型连续流动分析仪对水质总磷、总氰化物两个指标进行分析,所绘制的标准曲线线性良好,实验的检出限低于分析方法的检出限,实验中最后得到良好的精密度和准确度。连续流动分析仪操作简单,自动化程度高,测定数据稳定性好,分析速度快,试剂消耗量小,对环境污染少,对实验人员身体伤害小。尤其适用于大批量样品总磷、总氰化物的分析测试。In this paper, SEALAA3 HR continuous flow analyzer is used to analyze the two indexes of total phosphorus and total cyanide in water quality. The standard curve drawn has good linearity, and the detection limit of the experiment is lower than that of the analytical method. Finally, good precision and accuracy are obtained. Continuous flow analyzer has the advantages of simple operation, high degree of automation, good stability of the determination data, fast analysis speed, small reagent consumption, less pollution to the environment and less physical harm to the experimental personnel. It is especially suitable for the analysis and testing of total phosphorus and cyanide in large quantities of sample.
