摘要
在氨性介质下采用过氧化氢掩蔽高含量钴,以过硫酸铵——丁二酮肟光度法测定钴基合金中常量的镍,无须分离镍,实现了在大量钴存在下对镍的测定。
A new method was inctroduced to measure constant quantity of nickel by dimethylglyoxime spectrophotometry. The interference of Co( II ) for this system was studied and NH3 · H2O-H2O2 system was selected as a masking agent for Co( II)〈2 mg without interfering the determination of nickel. The nickel was directly detected without the process of separation.
