ABSTRACT
In this study, the sorption of malachite green, a basic dye onto sea shell was studied by performing batch kinetic sorption experiments. The equilibrium kinetic data were analyzed using the pseudo-second-order kinetic model. A comparison between linear least-squares method and non-linear regression method of estimating the kinetic parameters was examined. Four pseudo-second-order kinetic linear equations were discussed. Kinetic parameters obtained from four kinetic linear equations using the linear method differed. Type 1 pseudo-second-order kinetic model very well represented the kinetic uptake of malachite green by sea shell while Type 4 exhibited the worst fit. Present investigation showed that the non-linear method may be a better way to determine the kinetic parameters.
