本方法适用于各类特殊青铜(包括铝青铜、铍青铜、硅青铜、锰青铜、镉青铜、铬青铜、铅青铜、锑青铜等八类)及白铜中主要合金元素和杂质元素的分析。各类特殊青铜及白铜的牌号化学成份见附表。一、铜的测定 (甲、恒电流电解法) 铜可以在酸性或氨性溶液中电解析出,但定量测定通常是在酸性溶液中进行,因此下面只讨论在酸性
The method is suitable for the analysis of all kinds of special bronze (including aluminum bronze, beryllium bronze, silicon bronze, manganese bronze, cadmium bronze, chrome bronze, lead bronze and antimony bronze, etc.) and the main alloying elements and impurity elements in white copper. Various types of special bronze and copper grade chemical composition see Schedule. First, the determination of copper (A, constant current electrolysis) Copper can be electrolyzed in acidic or ammonia solution, but the quantitative determination is usually carried out in acidic solution, so the following discussion only in the acidic
