摘　　要：对硅酸盐中非沸石类矿物进行的晶体结构特征分析发现，某些链层状硅酸盐矿物（如坡缕石和海泡石）、钛硅酸盐中的硅钛铌钠石、硅钛铌钠矿、钙霞石、方钠石等，以及锰、锆、钒、钇硅酸盐矿物中的水硅钡锰石、堇青石、水钠锆石、水硅钒钙石等矿物中都存在有孔道结构，其孔道直径为0．25～1.0nm。本文综述了这些孔道结构矿物吸附和交换有害重金属离子、催化阵解有机污染物的环境功能和属性。The crystal texture analyses of non-zeolite silicate minerals indicate that channel structures are existed in some layer-chain silicate minerals such as palygorskite and sepiolite, some titanium silicates such as zorite and nenadkevichite, some feldspathoid minerals such as cancrinite and sodalite, some Mn-, Zr-, V-, Y-bearing silicate minerals such as verplanckite, cordierite, lemoynite, cavansite, pentagogonite, monteregianite, with their channel sizes varying from 0.25 nm to 1.0 nm. This paper has summarized the environmental functions and features of these channel structure-bearing silicate minerals in surface adsorption and ion exchange of heavy metal ions, and catalytic degradation of organic pollutants in environment.
