在２９３．１５－３３８．１５Ｋ范围内，溶液初始ｐＨ值为２、３和４条件下，用静态法系统地研究了铝在钠蒙脱土的吸附等温线及ｐＨ值、温度对吸附反应的影响。吸附等温线可用Ｌａｎｇｍｕｉｒ模型描述，吸附在粘土表面的铝除Ａｌ３＋形式外，还有水解产物形式（羟基铝）。根据ｐＨ变化估算了反应过程中，粘土边缘吸附的Ｈ＋，吸附于粘土表面Ａｌ３＋的水解所束缚的ＯＨ－和表面水解度。对三价离子与粘土的相互作用机理及ｐＨ对吸附的影响进行了研究。
In the range of 293.15-338.15K, the initial pH value of the solution is 2, 3 and 4 conditions, the static method was used to systematically study the adsorption isotherms and pH values of aluminum in sodium montmorillonite, influences. The adsorption isotherms can be described by the Langmuir model. The aluminum adsorbed on the clay surface is in the form of the hydrolysates (hydroxy aluminum) in addition to the Al3 + form. According to the change of pH, the adsorption of H + on the edge of clay and the OH- bound by the hydrolysis of Al3 + adsorbed on the clay surface and the degree of surface hydrolysis were estimated during the reaction. The interaction mechanism between trivalent ions and clay and the influence of pH on adsorption were studied.
