摘　　要：通过比较湿化消解法与微波消解法两种样品前处理方式,采用电感耦合等离子体发射光谱仪进行测定,建立了有机肥料中全硫含量的检测方法。湿化消解前处理试验样品,ICP-OES测定方法的检出限为0.075μg/mL,平均回收率97.9%;微波消解前处理试验样品,ICP-OES测定方法的检出限为0.058μg/mL,平均回收率为97.8%;2种前处理方法的测定结果的相对标准偏差在0.78%~4.75%,表明2种前处理方式可行。By comparing two kinds of pretreatment methods, such as wet digestion method and microwave digestion method,the determination method of total sulfur in organic fertilizer was established by inductively coupled plasma emission spectrometer. The test sample for pretreatment of wet digestion, the detection limit of icp-oes is 0.075 μg/mL, the average recovery rate is 97.9%; pretreatment test sample of microwave digestion, the detection limit of icp-oes is 0.058 μg/mL, the average recovery rate is 97.8%. The relative standard deviation of the two pretreatment methods in 0.78% ~4. 75%, and the results show that the satisfactory results can be obtained from both pretreatment ways.
