Method for quantitative analysis of copper concentration in copper-containing nickel chloride solution

摘要

PROBLEM TO BE SOLVED: To provide a quantitative analysis method of copper concentration in a copper-containing nickel chloride solution obtained in a chlorine exuding process of a nickel smelting method.;SOLUTION: The quantitative analysis method of copper concentration in a copper-containing nickel chloride solution includes the steps of: adding a solution including chloride ion to a copper-containing nickel chloride solution to obtain a diluted solution; measuring the absorbancy of the diluted solution; and calculating the copper concentration in the copper-containing nickel chloride solution from the acquired absorbancy.;COPYRIGHT: (C)2015,JPO&INPIT
