摘　　要：提出了氢化物发生电感耦合等离子体原子发射光谱法（ＩＣＰＡＥＳ）测定多金属矿石中的痕量Ｓｎ的方法．选用酒石酸作介质，考察了不同酸介质及浓度对氢化物发生效率的影响，试验了共存元素的干扰情况．方法的检出限为１．６×１０－１０ｇ／ｍＬ，精密度（ＲＳＤ）为０．７２％，标样分析结果满意．A method for the determination of trace Sn by hydride Generation ICPAES has been described. The influence of ICPAES operating conditions,acidic media and concentration of NaBH 4 solution have been studied. Experimental conditions were discussed and the influence of coexisting elements were investigated. The detection limit is 1.6×10 -10 g/mL and relative standard deviative 0.72%. This method has been applied to the analysis of eight standard reference multimetal ore samples and the results were in good agreement with thd recommended values.
