由于氧瓶燃烧法具有简便、快速、清洁等优点,因此在有机元素(包括部分金属元素)测定中,该分解法得到了广泛的应用。可是当用它来分解有机铅化合物时,因有铂-铅合金的形成,使此分解法丧失了实用价值。至今,分析工作者仍在寻找分解有机铅化合物的有效方法。A.Campiglio提出了样品先后用HNO_3两次、H_2O_2两次、HCIO_4一次、HNO_3-HCIO_4一次处理的消化分解法。显然,这是相当繁琐的。本文介绍的是不生成铂-铅合金的氧瓶燃烧和络合滴定来测定有机铅化合物中铅的新方法。该法是基于:有机铅
Due to the advantages of simple, rapid and clean oxygen cylinder combustion method, the decomposition method has been widely used in the determination of organic elements (including some metal elements). However, when it is used to decompose organic lead compounds, due to the formation of platinum-lead alloy, the decomposition method has lost its practical value. To date, analysts are still looking for effective ways to decompose organic lead compounds. A. Campiglio proposed a sample digestion method with HNO 3 twice, H 2 O 2 twice, once with HCIO 4 and once with HNO 3 -HCIO 4. Obviously, this is quite tedious. This article describes a new method for the determination of lead in organic lead compounds without oxygen-flask combustion and complexometric titration of platinum-lead alloys. The law is based on: organic lead
