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XRD的d_(060)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。
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.
