Abstract: In this paper, the analytical methods for determining cupferron with a standard copper solution or copper in alloy with standard cupferron by oscillopolarographic titration have been presented. The methods are rapid and accurate, and the end point is sharp. Satisfactory results can be obtained for determination of copper in copper alloy. The variation coefficients are 0. 07%~0. 17%. The kinetic behaviour of the cupferron in the instance of ultraviolet irradiation has also been studied.
