Abstract
In this work the recently published experimental data on the sorption capacity of expanded perlite to crude oil were correlated with the equilibrium isotherm of Langmuir, Freudlich, Tempkin and the three parameter Redlich-Peterson isotherms. The results obtained from each specified isotherms were compared and accuracy of the models were favorably discussed. Accuracy of each model was obtaining function. The effect of type of objective function on the final results was investigated. To bring up the idea the ERAV, ERRSQ, HYBRID, MPSD and Chi-Square objective function were used and the accuracy obtained using each objective function. The results showed the Redlich-Peterson model can better represent the equilibrium isotherm data for the crude oil to be up taken on the expanded perlite.
