✦ Synopsis

The kinetics of the oxidative destruction of cobalt phthalocyanine derivatives in aqueous solutions has been investigated in the concentration interval 10^−4^–10^−5^ M as a function of the concentration of alkali and the partial pressure of oxygen in the system. The kinetic equation for the initial solution bleaching rate is obtained. A mechanism of cobalt phthalocyanine destruction involving an intermediate Co (II) → Co (III) oxidation step is suggested.
