通过锆交联蒙脱土的X射线衍射、阳离子交换量及孔径分布等实验测定,利用部分无序层状结构的衍射公式,建立了相应的三维统计结构模型.交联剂中Zr(Ⅳ)主要以四聚及三聚的方式存在,在与Na-Mt交联过程中,四聚及三聚Zr(Ⅳ)离子先吸附一定量的水,与水共同支撑开蒙脱土层,使层间距分别达到2.55nm和2.10nm,如此层间距的层在整体结构中分别占35％和27％.水分子进入了其余层间域,层间距为1.26nm. By means of X-ray diffraction, cation exchange capacity and pore size distribution of zirconium-crosslinked montmorillonite, a three-dimensional statistical structure model was established by using the diffraction formula of partially disordered layered structure.The Zr (Ⅳ) Mainly tetrameric and trimerism exist, in the process of crosslinking with Na-Mt, tetrameric and trimeric Zr (Ⅳ) ions first adsorbed a certain amount of water, together with the water support montmorillonite layer, the layer spacing Respectively reach 2.55nm and 2.10nm, so that the layer spacing in the overall structure of the layer accounted for 35% and 27%, respectively. The water molecules into the rest of the interlayer, the layer spacing of 1.26nm.
