摘　　要：吸附与分离是目前化工生产中十分重要的过程。针对目前常见的几种吸附与分离的方法,对比了几种方法的优劣。由于天然粘土矿物产量丰富,具备原始的多孔性,是制备优异吸附性能吸附剂的潜在材料。对几种典型粘土矿物的结构、微孔/介孔性质、表面基团特性做了展开讨论。针对典型的二氧化碳等几种气体分子的特性,详细评论了近年来多孔粘土矿物作为气体吸附剂的研究进展,并对相关的其他最新研究成果进行了对比评论。从影响多孔粘土矿物吸附性能的多种重要参数(吸附位点数量与类型、吸附质浓度、pH值、环境温度以及粘土矿物层间是否有有机物附着情况等)的角度,针对近年的研究成果展开讨论与对比。在探讨目前研究进展的基础上,对未来的多孔粘土矿物作为吸附剂的研究方向提出了建议。Adsorption and separation are currently very important processes in chemical production.The advantages and disadvantages of several commonly used adsorption and separation methods are compared.As natural clay minerals are abundant in production and have original porosity,they are potential adsorbent materials with excellent adsorption performance.The structure,micropore/mesopore properties and surface group properties of several typical clay minerals are discussed.In view of the characteristics of several typical gas molecules,such as carbon dioxide,the research progress of porous clay minerals as gas adsorbents in recent years is reviewed in detail,as well as the comparative review of other recent research results.From the perspective of many important parameters affecting porous clay minerals(the number and type of adsorption sites,the concentration of adsorbate,pH value,environmental temperature,and whether organic matter is attached between layers of clay minerals),the research results in recent years are discussed and compared.Some suggestions on the future research direction of porous clay minerals as adsorbents are put forward.
