Title of the articleMetal coatings based on complex compounds of copper(II) with nitrilotrimethylene phosphonic acid
Abstract.Problem statement. The aim of the study was to study the complexation processes of copper (II) with nitrilotrimethylene phosphonic acid and to identify the possibility of using nitrilotrimethylene phosphonic acid as copper (II) ion ligands to obtain stable solutions of chemical copper plating. Results. The formation of copper(II) complexes with nitrilotrimethylene phosphonic acid was studied by electron paramagnetic resonance (EPR). The distribution of complex forms based on the processing of EPR measurements was studied in the form of the dependence dP/ dpH - f (pH), where P is the parameter of the EPR spectrum. The compositions were established and the stability constants of complexes in various media were calculated. Conclusions. The significance of the results obtained for the construction industry lies in the fact that new materials have been studied on the basis of complexes of copper with nitrilotrimethylene phosphonic acid. It has been established that nitrilotrimethylene phosphonic acid forms stable complex compounds with copper ions and is a promising material for the preparation of protective and decorative metal-polymer coatings on the surface of products used in the construction industry.
Keywords.metal coatings, electron paramagnetic resonance, stability, copper plating, ligand, nitrilotrimethylene phosphonic acid.
