Abstract
In this article, the effect of different adsorption isotherms on the prediction of energy distribution function was considered. It is known that the adsorption integral equation has two parts, kernel (isotherm) and distribution function, in which the energy distribution function can be obtained from the solution of this equation. The important isotherms (kernels) such as Sips, Toth and Unilan were considered. The above isotherms have substituted in the integral equation as kernels and then by using the linear regularization method and inverse theory, the prediction of energy distribution function was performed. The results illustrated that the Sips isotherm have negative effect on the prediction of energy distribution function and the Toth isotherm has performed very well at high levels of stochastic errors. Also, the Unilan isotherm can predict the energy distribution function successfully in all cases.
