Аннотация:When accelerated electrons were irradiated with aqueous solutions of cadmium and lead salts containing methyl alcohol, metal precipitates with densities of 1.17 and 1.1 g/cm3 were obtained and porosities of 86.5 and 90.3%, respectively, and greater surface area. The process of metal deposition was studied and the radiation–chemical yields were calculated, which amounted to (1.7 ± 0.2) × 10–2 and (3.4 ± 0.3) × 10–2 g per 1 kGy for cadmium and lead, respectively, and 1.56 ± 0.05 metal atoms per 100 eV of absorbed radiation energy. The developed method can be promising for obtaining precipitation of pure and amorphous metals from aqueous solutions of their salts, for developing technologies for treating water effluents containing toxic metals, as well as for using porous cadmium and lead in the manufacture of electrical devices.
