The adsorption of four adsorptiochromic spiropyrans to many solids (silica gel, silicic acid, fumed silica, alumina, microcrystalline cellulose, talc, titanium dioxide) was studied at 25 degrees C from cyclohexane solution. Nineteen adsorption isotherms were determined; and the binding data were fitted to the Langmuir equation. A model for binding of adsorptiochromic substances is described, and the parameters of the model are related to the experimental binding constant K.
在25摄氏度下，研究了四种吸附变色螺吡喃从环己烷溶液中对多种固体（硅胶、硅酸、气相二氧化硅、氧化铝、微晶纤维素、滑石、二氧化钛）的吸附。测定了19种吸附等温线；并将结合数据拟合到朗缪尔方程。描述了吸附变色物质的结合模型，且该模型的参数与实验结合常数K相关。
