摘　　要：替代传统手工法,建立了紫外分光光度法和超高效液相色谱-质谱法测定水中的丁基黄原酸的方法,与传统的分光光度法相比,这两种方法具有较高的准确度和精密度,操作简便、不污染环境。紫外分光光度法检出限为0.005 mg/L、测定上限为12.00 mg/L。超高效液相色谱-质谱法,水样过滤后就可直接测定,检出限为0.2μg/L,在0.5 g/L^50 g/L范围内线性良好,准确度高,加标回收率为90.1%~97.0%,精密度好,相对标准偏差为2.3%~3.4%,适用于水中丁基黄原酸的快速监测。The UPLC-MS and UV were established for determination of butyl xanthate in ground water. Comparing with the traditional methods,these two methods have high accuracy and precision,simple operation and no pollution. The UV determination limit is 0. 005 mg /L. With UPLC-MS,water samples can be determined directly after filtration without enrichment. It shows better linearity at a concentration range of 0. 5 to 50 g /L. The relative standard deviation is 2. 3% ～ 3. 4%,while the average recoveries are from 90. 1% to 97. 0%,and the method determination limit is 0. 2 μg /L.
