摘要
The adsorption properties of sodium and pyridinium montmorillonites are studied. It is shown that, in the temperature range 293-773 K, the limiting value of benzene adsorption on sodium montmorillonite slightly decreases and the specific surface area changes insignificantly, while these parameters for pyridinium montmorillonite increase by 1.3 and 1.6 times, respectively, within the interval 293-423 K. The dependences of the heat of adsorption on the amount of adsorbed benzene are determined from the isosteres of benzene adsorption and desorption on montmorillonite samples dehydrated at 373 K.
