It is found that for lead ions the increase of the coating growth rate is caused by the decrease of the interphase surface energy in the system nucleus-solution. For cadmium and amino acid ions the decrease of the growth rate is caused by blocking of the growth positions on the surface of crystalline nuclei. Lead and cadmium ions increase the coating crystallinity, whereas amino acid diminishes it. With the growth of the concentration of both organic and inorganic impurities the coating porosity increases.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
