Comparison of Different Methods for Linear Regression of Pseudo Second Order Adsorption Kinetics of Cadmium

The present paper would discuss the four linear regression of kinetic model of pseudo second order to describe the adsorption phenomenon. The adsorption parameters have been estimated by means of nonlinear method of pseudo second order as well as four linear regression methods are assessed. The results showed that, the nonlinear method of pseudo second order is a suitable method in estimating of adsorption parameters. A type 1 pseudo second order linear kinetic model has the highest coefficient of determination. It was also found that, among the regression methods, all of them except the regression type 2 would be useful recommendation for estimation of adsorption parameters.
