吸附法从盐湖卤水中提锂的研究进展

摘要

综述了有机、无机两大类吸附剂从盐湖卤水中吸附提锂的研究现状，特别综述了层状吸附剂、无定形氢氧化物吸附剂、锑酸盐吸附剂、铝盐吸附剂和离子筛型吸附剂等的研究应用现状，重点对比了国内外吸附法提锂的工艺技术及各类吸附剂的优、缺点，分析了现存吸附法提锂工艺中存在的一些问题，并从离子筛吸附剂合成条件、粉末状吸附剂造粒方式和吸附剂再生等方面建议了吸附法卤水提锂的改进方向。%The research progress on extracting lithium from salt lake brines by organic and inorganic adsorbents was introduced, the application of layered adsorbent, amorphous hydroxide adsorbent antimonate adsorbent, aluminum salt adsorbent and ionic-sieve sorbent was reviewed, the adsorption methods were contrasted especially. The problems existed in the adsorption methods at present were analyzed, the recommendations in synthesis condition, granulation method and utilization were suggested.
