摘　　要：针对低浓度含铼淋洗液中铼的回收进行了树脂吸附和解吸试验研究。通过研究对比旧树脂和新型树脂,得出合适的吸附和解吸条件。同时通过对温度、流速、解吸浓度等因素进行研究。结果表明,随着氨水浓度升高至3%时,解吸率可升高到98.54%。同时温度越低,流速越小,越有利于铼吸附。In this paper,resin adsorption and desorption experiments were carried out for the recovery of rhenium from low concentration rhenium leaching solution.The suitable adsorption and desorption conditions were obtained by comparing the old resin with the new resin.At the same time,temperature,flow rate,desorption concentration and other factors were studied.The results showed that the desorption rate could raise to 98.54%while ammonia concentration was increased to 3%.At the same time,the lower the temperature,the smaller the flow rate,the more favorable to rhenium adsorption.
