摘要
介绍了采用电感耦合等离子体原子发射光谱仪直接测定粗铅中的锑、铜、铋的方法,以硝酸-酒石酸消解试样,在10%硝酸介质中进行标准基体匹配,选择合适谱线进行测定,结果显示检出限低,回收率好,相对标准偏差较小,且测定范围广。
This paper introduces the determination method of antimony, copper and bismuth in crude lead by ICPAES. In this determination method,we dissolve the samples by nitric acid and tartaric acid,match standard substrate in 10% nitric acid and choose the right lines. The results show that this method has low detection limit, good recovery rate, small relative standard deviation and extensive measuring range.
