摘要
本文研究了痕量元素硒和碲在稀盐酸体系中经７３２型阳离子交换树胎的分离行为。经分离后的试液，用催化极谱法分别测定硒和碲。方法具有很高的灵敏度和重现性。硒的最低检测限为０．１ｎｇ／ｍｌ，碲为０．０ｌｎｇ／ｍｌ。测硒、碲的相对标准偏差分别为３．５％和１．５％。方法用于黄铁矿单矿物的分析，结果良好。
he separation of trace Se and Te in diluted HCl system by 732 cation exchange resinhas bee described． Se and Te can be deter mined （respectively in two deterination sysem ）by cat-alytic polarographic wave after separation. The method has high sensitivity and reproducibility. Thedetection limits of Se and Te are 0．1ng／ml and 0．01ng／ml respectively. The relative standard devi－ation is 3．5％for Se、1．5％for Te.The methed has been used for determination of pyrite samples withsatisfactory results.
