摘要
采用强酸性阳离子交换树脂分离富集了多金属铜矿石中的铜、磷元素,通过实验探究了强酸性阳离子树脂分离富集矿石中磷元素的条件,选择合适的分析谱线,用ICP-OES测定。运用该方法对多金属铜矿石一级标准物质(GBW 07233、GBW 07166)中的磷元素进行了测定,结果的相对标准偏差分别为2.53%和1.58%,其加标回收率为88.25%和93.50%。
The copper and phosphorus in polymetallic copper ore were separated and enriched by strong acid cation exchange resin, the optimal conditions of enriching phosphorus in ore were confirmed by the experiments. Choosing the appropriate analytical spectral lines, the trace phosphorus was determined by ICP-OES. The phosphorus of primary standard substance polymetallic metal copper （GBW 07233, GBW 07166） was determined by this method, the results of the relative standard deviations were respectively 2. 53% and 1. 58% ,and the recoveries were in the range of 88.25%-93.50%.
