Abstract

The catalytic properties of Mn(II)-histidine complexes for the oxidation of indigo carmine by H2O2 have been studied. It has been shown that the complex Mn(II) (Histidine)2 existing in as a dimer is the true catalyst but at high concentration of the reactant the reaction is inhibited because of complex formation between the reactant and the catalyst.

Abstract

Исследовали каталитические свойства комплексов Mn(II)-хистидин в окислении индигокармина перекисью водорода. Показано, что комплекс Mn(II)·(хистидин)2 играет роль катализатора. Однако, при высоких концентрациях реагентов реакция ингибируется комплексом между катализатором и реагентом.
