Title: Method for measuring concentrations of chelate agent and hydroxide ion in chemical copper plating bath
Inventor: HASEGAWA KIYOSHI
IPC: G01N31/16
Filed: 1990-05-31
Abstract: PURPOSE:To simply and accurately measure the concns. of the chelate agent and hydroxide ion in a chemical copper plating bath by titrating the chemical copper plating solution with an aqueous solution of a heavy metal ion. CONSTITUTION:When an aqueous solution of a salt of a heavy metal ion is added to a definite amount of the sample solution from a chemical copper plating solution, first of all, the reaction of a chelating agent not forming a chelate along with a copper ion with the heavy metal ion advances and, simultaneously with the completion of this reaction, the reaction of the heavy metal ion with a hydroxide ion advances. Since the former reaction is low in a pH change and the latter reaction is large in a pH change, by titrating a definite amount of the chemical copper plating bath with the aqueous solution of the salt of the heavy metal ion and detecting the pH of the mixed solution at the same time, the final points of both of the former reaction and the latter reaction can be known and the concn. of the chelating agent and that of the hydroxide ion can be measured at once.
