摘　　要：建立了王水密闭溶矿-电感耦合等离子体原子发射光谱法测定锑矿石中锑的方法.研究了溶矿时间、溶矿温度、溶液的酸度、基体效应对测定的影响.样品的相对误差在1.10％～13.33％,11次独立测定的相对标准偏差均小于2％.经标准物质验证,结果满意.The method for determining the concentrations of Sb in stibium ore by inductively coupled plasma-atomic emission spectrometry（ICP-AES） with closed digestion using aqua regia is reported in this paper. The influence of digestion time, digestion temperature, solution acidity and matrix effect on the determination were studied. The relative errors （RE） in the sample are between 1.10%-13.33%. The relative standard deviation of 11 independent determination is less than 2%. The accuracy and precision of the method are validated by reference materials and the results are satisfactory.
