利用PAN-3螯合纤维富集分离微量Sb(Ⅲ)和Sb(Ⅴ)的ICP光谱分析

ICP-AES Analysis Enriches and Separates Trace Sb(Ⅲ)and Sb(Ⅴ)by Means of PAN-3 Chelate Fiber

本文建立了利用 PAN-3螯合纤维富集分离微量 Sb(Ⅱ)和 Sb(V)的 ICP-AES 分析法,研究了 PAN-3对 Sb(Ⅲ)和 Sb(Ⅴ)的定量富集酸度、洗脱酸度、富集介质用量和共存离子的干扰及消除.进行了低浓度 Sb(Ⅲ)和 Sb(Ⅴ)的富集、误差统计和样品分析,获得了满意结果.

The ICP-AES analytical method being able to enrich and separate traceSb(Ⅲ)and Sb(Ⅴ)is established through the use of PAN-3 chelate fiber.The acidity of quantitative enrichment,the acidity of desorption,the usefulamount of the enrichment medium,as well as interference and eliminationof co-existent ions on Sb(Ⅲ)and Sb(Ⅴ)are investigated.The enrichmentof lower concentration Sb(Ⅲ,Ⅴ),the error statistics and analysis samplesare also achieved with satisfactory results.
