摘要：

The adsorption of polyacrylic acid on copper(II) oxide powder from aqueous solutions was studied. The amount of the adsorbed polymer was shown to increase with time reaching its maximum over 6-7 min. The desorption kinetics of copper polyacrylates was studied by measuring variations in copper ion concentration in the solution. The rate of desorption was found to be independent of the initial concentration of polyacrylic acid. A decrease in the dispersed phase concentration did not actually affect the initial rate of the polymer desorption. However, it caused a drastic fall in the rate of desorption after 1-1.5 min. A mathematical model was proposed for describing the experimental data.
