| 摘 要： | 对不同镍含量的镍取代云母蒙脱石（ＮｉＳＭＭ）样品，通过ＸＲＤ分析，阳离子交换容量和比表面积测定，证明随着镍含量的增加，镍越来越多地进入到单元层结构中。ＮｉＳＭＭ具有与天然蒙脱石相同的层状结构，其层间填充着可被交换的阳离子。这些阳离子大多数是ＮＨ４＾＋。ＸＲＤ的ｄ０６０值和红外光谱的骨架振动吸收带进一步表明，镍是进入到单元层中八面体片的六配位中心离子的位置上。ＮｉＳＭＭ的结构稳定性高于天然蒙脱石。

| Abstract: | The structure of NiSM M(Nickel-Substituted Mica Montmorillonite) samplesprepared under different conditions were characterized by means of XRD analysis,CEC andsurface area measurements,and IR analysis. It was shown that mote nickel enters the layerstructure of NiSM M when more nickel is added to starting matcrials for the synthesis. NIS-MM has the same layer structure as that in natural smectite.There are exchangable cationsbetween the layers, most of which are The d_(060) value of XRD pattern and the skeletalvibration of IR spectra reveal that nickel ions are located at the centers of octahedra inthe unit layer of NiSMM. |
