| 摘 要： | 本文在氢溴酸介质中，以氯化三辛基甲胺（以下简称ＴＯＭＡ．ＣＬ）的二甲苯溶液为萃取剂，详细研究了微量碲的萃取分离和测定条件。在同一试液中，经两步萃取，分离后，用光度法测定样品中微量碲。此方法简便。仪器简单，实用性强，易于推广，选择性好，灵敏度高。

| Abstract: | Using dimethylbenzene solution of TOMA.CL as extraction agcnt,the conditions of extraction and determination of trace-tellurium in hydrobromic acid medium were studied.By spectrophotometric method,after twice extraction,the trace-tellurium in the same sample was determined.Results showed that this method was simple and effective with higher sensitivity and selection. |
