[Ni(L-L)(3)]SO(4)和[Ni(L-L)(3)]Cl(2)的插层反应(L-L= 1,10-菲咯啉(phen),2,2 '-联吡啶(bpy))与钠基蒙脱土在不同的动态条件下如超声辐照、超声波、高压灭菌和剧烈搅拌下进行的反应表明,在超声辐照下,金属配合物的最大吸附发生在30 min内。含有phen配体的金属配合物显示出比含有bpy的金属配合物更高的吸附。最大吸附量约为粘土阳离子交换容量(CEC)的三倍。在较高量(>CEC)的金属络合物处理下,聚集(基底间距d(001)12.5 μ m)的Na-蒙脱石形成单层(基底间距d(001)17.6 μ m)物种,而预分散粘土则形成双层(基底间距d(001)>28 μ m)或假三层(基底间距d(001)>32 μ m)物种。双层物质在高达250 ℃下是热稳定的,并且在此温度以上形成单层物质。插层物种的热稳定性高于插层物种。X-射线衍射,紫外-可见,红外光谱,热分析和表面积测量用于表征的产品。版权所有2001学术出版社。
Intersalation reactions of the complexes [Ni(L-L)(3)]SO(4) and [Ni(L-L)(3)]Cl(2) (L-L=1,10-phenanthroline (phen), 2,2'-bipyridyl (bpy)), with Na-montmorillonite carried out under different dynamic conditions such as ultrasonic irradiation, refluxing, autoclaving, and vigorous stirring showed that under ultrasonic irradiation, maximum adsorption of the metal complexes occurred within a period of 30 min. Metal complexes containing the phen ligand showed higher adsorption than those containing bpy. Maximum adsorption up to about three times the cation exchange capacity (CEC) of the clay was observed. Aggregated (basal spacing d(001) 12.5 Å) Na-montmorillonite, in treatment with a higher amount (>CEC) of metal complexes, formed monolayered (basal spacing d(001) 17.6 Å) species, while with predispersed clay, bilayered (basal spacing d(001)>28 Å) or pseudo-trilayer (basal spacing d(001)>32 Å) species were formed. The bilayered species were thermally stable up to 250 degrees C and above this temperature monolayered species were formed. The thermal stability of the intersalated species was higher than that of the intercalated ones. X-ray diffraction, UV-visible, IR-spectroscopy, thermal analyses, and surface area measurements were used for characterization of the products. Copyright 2001 Academic Press.
