【摘要】 分析了国内外盐湖卤水开发和锂离子筛吸附剂研究现状,提出以多金属结核还原氨浸渣为原料制备价格低廉的锂离子筛,所合成离子筛具备尖晶石结构,吸附容量12.84 mg/g。对实际卤水锂的吸附率大于95%,分配系数大小顺序为Li+>>Ca2+>Mg2+>K+>Na+,锂离子的分配系数达19000,而其他离子的分配系数小于5。更多还原

【Abstract】 The exploitation status of salt lake brine and the study status of adsorbent for lithium ion-sieve are analyzed in domestic and foreign.Reduction ammonic leaching residue of polymetallic nodules are used to prepare low-priced lithium ion-sieve,with 12.84 mg/g of adsorbent capability and lager than 95% of the adsorbent rate.The distribution coefficient is Li+>>Ca2+>Mg2+>K+>Na+,and the distribution coefficient of lithium ion is 19000,the others are all less than 5.更多还原
