Study of complex formation copper (II) ions with polyacrylic acid
The process of interaction of copper ions with polyacrylic acid is investigated in this paper.It is shown that complexes are formed by the interaction of polyacrylic acid with copper ions (II) in a wide range of pH. At pH <4 the precipitate of complexes falls, the pH of the solution increases, water-soluble copper complexes (II) with polyacrylic acid are formed. The solubility of such complexes depends on the number of ionized carboxyl groups of the macromolecule.
