Complexation of amphoteric copolymer of 2-methyl-5-vinylpyridine-acrylic acid with copper(II) ions and catalase-like activity of polyampholyte-metal complexes

The interaction of polyampholyte based on 2-methyl-5-vinylpyridine and acrylic acid with copper(II) ions in aqueous solution has been investigated. Several types of complexes were formed, dependent on pH. The catalytic action of polyampholyte-copper(II) complex in hydrogen peroxide decomposition has...

Description
Summary:The interaction of polyampholyte based on 2-methyl-5-vinylpyridine and acrylic acid with copper(II) ions in aqueous solution has been investigated. Several types of complexes were formed, dependent on pH. The catalytic action of polyampholyte-copper(II) complex in hydrogen peroxide decomposition has been studied. The kinetic parameters and activation energy of this process were determined. The relation between the structure of complexes and their catalytic activity is also discussed.
