摘　　要：探讨了磁化前后，石油羧酸盐表面活性剂在高岭土表面静吸附规律的变化。实验发现，经磁化处理的石油羧酸盐表面活性剂，在高岭土表面的吸附速度变快，液固比变小，吸附等温线仍有最大值，但已大为下降，从而推断其吸附模式发生改变。The changes of the surface static adsorption acting on the surface of kaolinite by petroleum carboxylate surfactants, at and after the magnetization, are studied. It is found that the adsorption rate of magnetized petroleum carboxylate on surface of kaolinite is faster and L/S is smaller than that of unmagnetized surfactants. The adsorption isotherm curves still have a maximum, although it is decreased greatly. So it can be concluded that the adsorption mode has been changed.
