Paper Title:
Determination of Tin and Nickel Content in Pyrophosphate Tin-Nickel Alloy Plating Bath
  Abstract

Tin and nickel ions are in stable complexing form in Pyrophosphate tin-nickel alloy plating bath, this paper uses back-titration of Zn2+ standard solution to determine total amount of tin and nickel ions, and spectrophotometry to determine content of nickel ions in the bath to study interference and elimination methods of co-existing components. The results show that: eliminate the interference of pyrophosphate by heating the solution to hydrolyse and mask Sn4+ and Fe3+ effectively with triethanolamine, the total measurement error is about 0.91%, standard deviation is 0.0141; The recovery of determination for nickel ion content is 99.13%, and standard deviation is 0.0180; The method i-s simple, fast and is able to meet the analytical requirements for controlling the plating quality.
