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
In this paper, the extraction, separation and determination conditions of trace tellurium were studied in detail in hydrobromic acid medium with xylene solution of trioctylmethylamine chloride (hereinafter referred to as TOMA CL) as extractant. In the same test solution, after two steps of extraction, separation, spectrophotometric determination of trace amounts of tellurium. This method is simple. Instrument is simple, practical, easy to promote, good selectivity, high sensitivity
