Effects of Surface Heterogeneity in Adsorption from Binary Solutions on Modified Silica Gels

Effects of Surface Heterogeneity in Adsorption from Binary Solutions on Modified Silica Gels

The adsorption of benzene from cyclohexane solutions on modified silica gels is analysed using expressions derived from the model of adsorption of binary solutions on heterogeneous solid surfaces. The adsorption equation is found to represent the data for several systems and leads to a method for es...
