摘　　要：报道了采用ICP AES法测定矿石中的BeO。对试样的溶解进行了选择 ;考察了基体和无机酸对测定的影响。采用基体匹配法进行测定。在优化条件下 ,对三个试样进行测定 ,其相对标准偏差 (n =9)为 0 .2 8%;回收率为 97%～1 0 3 %。The determination of BeO in ores by ICP-AES was reported in this article. Dissolution methods were chosen and the effect of matrix and inorganic acid to the determination were examined. The matched matrix method was applied in the determination. Under optimized conditions, three samples were determined. The RSD (n=9) of this method was 0.28% and the recovery was examined from 97% to 103%.
