我们曾研究了在盐酸介质中,用非离子型表面活性剂烷基酚聚乙二醇醚及苯芴酮光度法测定微量锆的方法。在此基础上,本文研究了在盐酸介质中,以非离子型表面活性剂聚乙二醇辛基苯基醚(以下简称 OP-8) 及苯芴酮分光光度法测定微量铪的适宜条件。提出了一个操作简便、灵敏度高的新方法。络合物的摩尔吸光系数ε=1. 29×10~5、桑德尔灵敏度 S=0. 00138微克/厘米~2;入最大为535纳米、铪的含量在0-4微克/25毫升符合比耳定律。
We have studied the method for the determination of trace zirconium using the nonionic surfactant alkylphenol polyglycol ether and benzofluorenone in hydrochloric acid medium. On this basis, the suitable conditions for the determination of trace hafnium with non-ionic surfactant polyethylene glycol octylphenyl ether (hereinafter referred to as OP-8) and benzofluorenone spectrophotometry are studied in hydrochloric acid medium. A new method which is easy to operate and highly sensitive is proposed. Molar extinction coefficient of the complex ε = 1. 29 × 10 ~ 5, SANDAL sensitivity S = 0.00138 μg / cm ~ 2; into the maximum of 535 nm, hafnium content of 0-4 μg / 25 ml of the ratio Ear law.
