摘　　要：将流动注射分析技术与硫氰酸盐分光光度法相结合,建立了测定工业废水中钼的快速分析方法。在采样频率为80样/h时,检出限为0.08mg/L,线性范围为0～10mg/L。应用该方法测定工业废水样中的钼含量,相对标准偏差不大于1.3(n=5),加标回收率为96.6～98.1,测定结果与采用国家标准方法测定结果基本一致。A rapid method for determination of molybdenum in industrial wastewater by flow injection thiocyanate spectrophotometry was established. The detection limit was 0.08 mg/L at a sampling frequency of 80/h. Calibration curve was linear in the ranges of 0 - 10 mg/L. The proposed method was applied to the analysis of several industrial wastewater samples, with relative standard deviation less than 1.3% （n = 5 ） , and recoveries of 96.6% -98. t %. The determination results agree with those obtained by national standard method.
