After extraction separation of gold by MIBK, lead, copper, iron, nickel in gold plating bath were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES).
The lead concentration in Pb-Sn alloy plating bath was determined by standard additional atomic ab-sorption spectrometry, and the optimal determination conditions were obtained.
