| 摘 要： | 本工作提出在金盘(或金膜)电极上阳极溶出伏安法测定痕量碲,并对测定方法的灵敏度、精确度、回收率及其共存元素的干扰情况等进行了探索。为了测定天然水中ppt级的碲又采用样品事先经巯基棉分离、富集。在0.1M高氯酸底液中测得闽江水中8.1ng/1的碲,东海海水中1.8ng/1的碲,其平均回收误差在10%以下。

| Abstract: | In this work trace tellurium has been determined by the anodic strip-ping voltammetry on a gold plated electrode or on a gold film deposited ona glassy graphite electrode. Sensitivity, accuracy of the method, recoveryratio as well as the influence of the interfering coexistent elements are disc-ussed.The sample was previously separated and adsorbed through sulfhydrylcotton fiber. In O.1M perchloric acid medium the amount of tellurium inthe water of Min River and in East Sea have been determined to be 8.1 and 1.8 ng/1, respectively,with the recovery error less than 10%. |
