摘　　要：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。It is studied that the effect of adsorption time, temperatune and medium acidity on the performance of R\|519 resin for adsorbing rhenium. The results show that the process of R\|519 resin adsorbing rhenium busically agrees to Boyd/ fluid film diffusion model. The adsorption rate falls rapidly with the cocentration of HCl up. But the distribution falls.While the temperature is getting higher. The apparent enthalpy of adsorption reaction ΔH is -5.884 kJ/mol.
