Abstract

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.

水溶液中Pb 2+和Cd 2+离子的辐射化学还原过程中多孔金属沉积物的形成

摘要

当用含甲醇的镉和铅盐的水溶液照射加速电子时，得到的金属沉淀物的密度分别为1.17和1.1 g / cm ³，孔隙率分别为86.5和90.3％，并且表面积更大。研究了金属沉积的过程，并计算了辐射化学产率，分别为（1.7±0.2）×10 ^–2和（3.4±0.3）×10 ^–2镉和铅的每1 kGy克g和每100 eV吸收的辐射能1.56±0.05个金属原子。所开发的方法有望从其盐的水溶液中获得纯金属和非晶态金属的沉淀，开发用于处理含有毒金属的废水的技术，以及在电气设备的制造中使用多孔镉和铅的技术。
