通常天然水中铀的含量很低,一般需经予富集后,才能测定。使铀与有机化合物形成络合物,用活性炭吸附,是分离富集微量铀的一种简便而有效的方法,在微量铀的分析中已有应用,但使铀(Ⅵ)与酒石酸形成络合物,用活性炭吸附富集,以偶氮氯瞵Ⅲ分光光度法测定的方法,尚未见有报导。本文较系统地研究了这一方法的有关条件,提出了用于测定
Normally, the content of uranium in natural water is very low, and generally it needs to be enriched before it can be measured. Making uranium complex with organic compounds and adsorbing with activated carbon is a simple and effective method for separation and enrichment of trace uranium. Uranium has been used in the analysis of trace uranium, but uranium (Ⅵ) is complexed with tartaric acid Things, with activated carbon adsorption enrichment, with arsenic chloride 瞵 Ⅲ spectrophotometry method, has not been reported. This article systematically studied the conditions of this method, proposed for the determination
