摘　　要：建立了紫外荧光法检测复合肥中总硫含量的方法,样品前处理中使用无机酸-盐酸溶解试样。标准工作曲线相关线性良好,相关系数r0.999 4,测得两批试样的相对标准偏差分别为0.013%、0.016%,该方法能快速准确检测复合肥中总硫含量。A method for determination of total sulfur in compound fertilizer by ultraviolet fluorescencel was set- up. Sample pretreatment was made with inorganic acid - hydrochloric acid to dissolve the sample. The standard cali- bration curve was good with the linear correlation coefficient r = 0.999 4, and the relative standard deviations of two batches samples were 0. 012%, 0. 016%. This method could rapidly and accurately detect acid soluble total sulfur content in the compound fertilizer.
