本方法适用于各类锡青铜及锡磷青铜中主要合金元素和杂质元素分析。各类锡青铜及锡磷青铜的牌号及化学成份见附表。一、铜的测定方法与《黄铜快速分析方法》中所述相同(详见本刊1972年第1期第24页)。二、铅及锌的测定锡青铜中铅及锌的含量相差不大,因此可以用络合滴定法在同一份试样溶液中作铅、锌的连续测定。
The method is suitable for the analysis of alloying elements and impurity elements in various types of tin bronze and tin-phosphor bronze. Various types of tin bronze and tin phosphorus bronze grades and chemical composition see Schedule. First, the determination of copper and “brass rapid analysis method” described in the same (see the first issue of 1972 No. 24). Second, the determination of lead and zinc Tin bronze in the lead and zinc content is not much difference, so you can use complexation titration in the same sample solution for lead, zinc continuous determination.
