摘要
提出了火焰原子吸收光谱法测定重晶石中锌、铜和铁的方法 ,相对标准偏差为 1 .7%～7.3% ,加标回收率在 95.2 %～ 1 0 3.2 %之间。特征浓度锌为 0 .0 1 0 μg·ml-1/1 % ,铜为 0 .0 35μg·ml-1/1 % ,铁为 0 .0 67μg· ml-1/1 %。方法简便、准确、可靠。
A simple and accurate method for the determination of zinc, copper and iron in barite by FAAS is reported in this paper. The characteristic concentration for zinc, copper and iron are found to be 0.010μg·ml -1 /1%, 0.035μg·ml -1 /1% and 0.067μg·ml -1 /1% respectively. The RSD′s found are between 1.7%~7.3% and the recoveries found by the standard addition method are between 95.2%~103.2%.
