吸光光度法分析铝青铜中夹杂物

Determination of Aluminum-Bronze with Spectrophotometric Methods

借助吸光光度法 ,运用电化学原理 ,对用电解法分析铝青铜中夹杂物作了初步研究。结果表明 ,在由CuSO4 ,H3 PO4 及柠檬酸组成的溶液中 ,当pH =2～ 3,2 5℃ 2A/dm2 条件下将铜合金进行电解分离 ,用重量法分析夹杂物重量 ,用吸光光度法测定各组分量 ,操作简便 。

The spectrophotometry was applied for determining sandwich of aluminum-bronze with electro-analysis.The results showed that spectrophotometric and gravimetric analysis methods were easy and accurate.
