摘要
在不同pH值的电解质水溶液中,测定了超微细粘土的交换率和分维数随pH值的 变化.研究了锌离子与超微细粘土颗粒的交换等温线,在较大的浓度范围内出现台阶性吸 附.用小角度X射线衍射法(SAXS)研究了超微细粘土(高岭石)及其与锌离子交换后 的分数维数.
The fractal dimension and exchanged ratio of clay minerals (Kaolinite) particles that are exchanged with zinc ions are determined with PH values in strong electrolyte (seawater) by small angle X-ray scatter method. It is found that the isotherms between zinc ions and kaolinite have stepwise adsorption in major concentration.
