Abstract : this paper , by analyzing the effect of differences of mineral structure of 2 1 layer minerals , the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation , reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges . the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals . the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity 文摘:分析2 1型礦物的結構差異、層間電荷性質以及在風化過程中某些性質的變化對層間陽離子吸引力的影響,對已有報道中一些矛盾的結果或不具普遍意義的結論進行了討論.得出幾個較為明確的結論:層間總電荷與四面體電荷所占比例大小共同決定礦物對層間陽離子的固定能力;原生礦物中八面體結構與層間陽離子固定間的關系對次生礦物而言,也許并不一致;八面體中可變價陽離子的氧化還原,可導致礦物固定陽離子能力發生較大變化

3 ) raman and ir spectroscopy techniques have been used to study kaolinite - organic intercalation mechanism . during the intercalation reaction , the original hydrogen bonds between the al ( o , oh ) ( , octahedral hydroxyl groups and the sio4 tetrahedral oxygens were broken , and the new hydrogen bonds between organic molecular and kaolinite were formed 甲酰胺和聚丙烯酰胺以c = o基與高嶺石內表面羥基形成氫鍵, nh基與高嶺石si - o基形成氫鍵并部分嵌入高嶺石的復三方孔洞。

So , the probability of adsorption of ldl to adsorbents increases in the presence of ca2 + . in addition , an octahedral coordination geometry that is beneficial to the adsorption for ldl may be formed around a calcium ion between neighboring sde ligands immobilized on paa 另外,從空間構象來考慮,當向吸附體系中加入caz ”后,固定于載體表面或其孔洞內的多個相鄰配體及其間隔臂分子圍繞鈣離子可能形成一個有利于l l結合的八面體結構,這樣也利于本吸附劑對ldl的吸附。
