研究了吸附时间、温度、介质酸度对R 5 19树脂吸附铼性能的影响。结果表明 ,该树脂吸附铼的过程基本符合Boyd液膜扩散模型 ,吸附速率随盐酸浓度的增加而急剧下降 ,分配比却随温度的升高而降低 ,吸附反应的表观热效应值ΔH为 -5 .884kJ/mol。
The effects of adsorption time, temperature and medium acidity on the adsorption of rhenium on R 5 19 resin were studied. The results showed that the adsorption of rhenium on the resin was in accordance with the Boyd liquid membrane diffusion model. The adsorption rate dropped sharply with the increase of hydrochloric acid concentration. However, the distribution ratio decreased with the increase of temperature. The apparent thermal effect ΔH of the adsorption reaction was -5 .884 kJ / mol.
