探讨用不同强度的正丁胺、3-甲基吡啶、吡啶等测定改性粘土表面酸总酸度的方法．用Langmuir吸附等温式来拟合非酸中心部位对有机碱的吸附，排除了非酸中心部位吸附的影响．可用于实际改性粘土体系的表面酸总酸度测定，是一项简捷的粘土表面酸测试新方法，其终点不受样品本身颜色的影响．
The method of determining the total acidity of modified clay surface with n-butylamine, 3-picoline and pyridine with different intensities is discussed. Langmuir adsorption isotherm was used to fit the adsorption of organic base at the non-acid center and eliminate the influence of non-acid center adsorption. The total acidity of surface acids, which can be used in practically modified clay systems, is a straightforward new method for the acid test of clay surfaces whose end point is unaffected by the color of the sample itself.
