摘要
研究了新型功能性阴离子交换树脂—— F1树脂吸附和解吸铼的性能。通过静态试验 ,考察了铼的介质酸度、温度、溶液铼浓度及时间对树脂吸附和解吸铼的影响 ;在动态试验中 ,考察了溶液铼浓度、溶液流速和解吸剂流速的影响。对解吸剂和掩蔽剂及其浓度的选择做了较详细的探索 ,并研究了树脂再生和循环使用情况。试验结果较理想 ,表明 F1树脂是一种很有发展前途的新功能离子交换树脂。
Adsorption and desorption of rhenium with new anion exchange resin——F1 resin have been studied.In static experiments,the effects of solution acidity,rhenium concentration,temperature and time on adsorptive and desorptive performances of F1 resin are examined.In dynamic experiments,the effects of rhenium concentration and flow speed of the solution on adsorption,and flow speed of eluent on desorption are examined.Strippant,screening agent and their concentration are determined.Regeneration and recycle of the resin are studied.The experimental results show that F1 resin has good adsorptive and desorptive performances to rhenium,and has a good future.
