ADSORPTION

UDC 541.183

A model of the polymolecular adsorption on homogeneous 
and inhomogeneous surfaces in the absence of lateral interactions 
and also with their allowance for the case of the homogeneous surface 
is presented. A procedure to calculate isotherms on the basis of statistical 
data on the substance distribution over the surface is suggested. 
The calculated dependences of the differential adsorption energy on 
the degree of filling and the isotherms are compared with the experimental 
data for the system benzene vapor-graphitized soot.
