用阿拉伯树胶增敏增溶分光光度测定痕量碲（ＩＶ）及其应用方国桢，刘黎（四川大学化学系，成都６１００６４）一、前言常量碲可用滴定分析，但选择性不高；对微、痕量碲测定，氢化物发生——ＡＡＳ法效果尚好，但需碲空心阴极灯；ＩＣＰ－ＡＥＳ法测Ｔｅ，再现性欠佳；伏... Determination of Trace Tellurium (IV) with Acacia by Sensitizing Solubilization Spectrophotometry and Its Application FANG Guozhen, LIU Li (Department of Chemistry, Sichuan University, Chengdu 610064) I. INTRODUCTION The constant tellurium can be analyzed by titration but its selectivity is not high. Determination of trace amounts of tellurium, hydride generation - AAS method is still good, but the need to tellurium hollow cathode lamp; ICP-AES method Te, poor reproducibility;
