Abstract

The kinetics of oxidative dissolution of copper at formation of dissimilar ligand complexes has been investigated. The kinetic parameters of the dissolution process were determined by the rotating disk method and quantitative determination of metal by photometric method with bis(cyclohexanone)oxalyl dihydrazone, and a mathematical model of the dependence of the rate of copper transition into solution on the process parameters was obtained.
