摘要
研究了自制粒状离子筛型锂吸附剂的吸附容量、洗脱性能和重复吸附洗脱时的稳定性。结果表明,吸附剂在纯锂盐溶液中的锂离子吸附容量为15.63 mg/g,在海水中的锂离子吸附容量为5.68 mg/g;洗脱剂盐酸的浓度越高,对吸附剂中锂离子的洗脱率越高,但同时离子筛的溶损率加大;吸附剂循环吸附洗脱时,吸附与洗脱性能较稳定,并可重复使用。
The adsorption capacity, elution properties and stability of the self - made granule ion - sieve type Li^＋ adsorbent were investigated. The results show that adsorptive capacity of the adsorbent reaches 15.56 mg per gram adsorbent in the pure lithium solution and 5.68 mg per gram adsorbent in the seawater respectively; the higher the concentration of HCl solution is, the higher the elution rate of Li^＋ on the adsorbent is;simultaneously, the adsorbent dissolving rate increases. The repeated experiments indicate that the adsorption and clution performances of the adsorbent are stable and the adsorbent can be reused.
