摘　　要：黄磷铁矿、磷钠铍石、磷方沸石、簇磷铁矿、磷锰钠石、水磷铈石和磷灰石是非硅元素的孔道结构矿物。[PO_4]四面体和[MO_n]多面体共用角顶构成杂多面体格架。形成一维或多堆沿一定方向分布的孔道结构,孔道内由水分子和其它金属或非金属离子占据。孔道结构的磷酸盐矿物具有类似沸石矿物的分子筛效应,可与其它有害元素进行离子交换、孔道过滤和表面吸附等功能,是另一类重要的环境矿物材料。Cacoxenite, beryllonite, viseite, beraunite, alluaudite, rhabdophane and apatite are non-silicon channel structural minerals. [PO_4] tetrahedra and [MO_n] polyhedra share the apexes or edges to form open structure along one direction or several directions. Water molecular and other anion or cation located in the channels. Phosphate minerals with channel structure are similar to zeolite minerals, having the functions of ionic exchange, porous filtration, absorption and adsorption, et al. They are the other i...
