摘　　要：利用吸附剂从卤水中提锂是目前最具发展潜力的提锂方式。综述了层状吸附剂、锑酸盐吸附剂、铝基吸附剂和离子筛型氧化物吸附剂的吸附机理、制备方法、吸附性能,并对比了各自的优缺点。指出吸附剂中以铝基吸附剂和离子筛型氧化物吸附剂的优势最为明显,但是都存在成粉末状、流动性及渗透性差、溶损率较高等缺点。因此,如何造粒以及如何降低溶损率将成为吸附法盐湖提锂技术的发展方向。The use of adsorbents to extract lithium from brine is currently the most promising lithium extraction method.The adsorption mechanism,preparation method and adsorption performance of layered adsorbent,antimonate adsorbent,aluminum-based adsorbent and ion sieve type oxide adsorbent were reviewed,and their advantages and disadvantages were compared.It was pointed out that the advantages of aluminum-based adsorbent and ion-screen oxide adsorbent were the most obvious in above adsorbents,but they both have the disadvantages of powdered shape,bad fluidity and permeability,and high solution loss etc..Therefore,how to granulate and how to reduce the dissolution loss will become the development direction of the lithium extraction technology of salt lake by adsorption.
