摘　　要：采用分光光度计和比色管 ,研究了以XO为显色剂并用双波长分光光度法测定电镀Zn Ni合金溶液中的Zn2 +与Ni2 +含量的方法 ,分析了测量波长与参比波长的选择、溶液酸度与显色条件、测量的线性范围以及有机络合剂和Fe3+等干扰因素的排除对测量结果的影响。实验结果证明 ,该方法是可行的 ,能连续测定镀液中的Zn2 +与Ni2Using XO agent as colorant,the continuous quantitative determination of Zn\+\{2+\} and Ni\+\{2+\} in Zn-Ni plating bath solution was studied by spectrophotometric means.The effects of reference wave length,color developing conditions,linear range of measurement solution acidity and the removal of interferential factors such as Fe\+\{3+\} and organic complexing agent were discussed.
