Abstract
Using 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.
