摘要
采用硝酸、酒石酸溶解样品,用电感耦合等离子炬-原子发射光谱法直接测定铅及铅合金中的铜、银、砷.该法测定速度快,测量结果的相对标准偏差为0.34%~0.49%,铜、银、砷的回收率分别为99.2%~116.7%、93.3%~101.1%、98.3%~116.0%.
The sample was digested with nitric acid and tartaric acid. Copper, silver, arsenic were directly determined by ICP - AES method. Meanwhile, the matrix effect was experimented, the interference of other elements was studied, the solve condition of the sample was discussed in detail. Therefore, the quick and accurate determination of copper, silver, arsenic in lead and lead alloys was realized with the RSD of 0.34%-0.49%. The recoveries of C u, Ag and As were 99.2%-116.7%, 93.3%-101. 1% and 98.3%-116.0% respectively.
