摘　　要：采用过氧化钠高温熔解含铅矿物样品,在盐酸介质(10%)中,采用电感耦合等离子体原子发射光谱法在波长为230.4nm、493.4nm处测定铅矿物中的钡。方法能有效消除铅的干扰,测定结果相对标准偏差小于5.0%,加标回收率在97.6%~102.0%之间,该法简便快速、结果准确、容易掌握、成本低。Sodium peroxide is adopted to melt lead-bearing ore sample with high temperature;the barium in the lead-bearing ore is determined when the wave length is 230.4 nm,493.4 nm by inductively coupled plasma atomic emission spectrometry,and in the hydrochloric acid media(10%).The method can eliminate lead interference effectively,the relative standard deviation of testing result is less than 5.0%,the adding standard recovery rate is between 97.6%~102.0%,the method is simple,rapid,accurate,easy to master with low cost.
