Biosorption behaviour of Mangifera indica biowaste as function of Pretreatment

Biosorption is a cost effective and clean process for the removal of toxic species. In this paper, an attempt has been made to make use of Mangifera indica biowaste for removal of cationic species. Different characterization techniques were used to characterize as well as understand the sorption process. The sorption behaviour was found to be dependent on the sorbent size with higher efficiency seen for samples with least size. The sorption of the dyes was found to be dependent on the nature of dye. The studies were carried out around pH ~ 6 as the pzc was obtained as 5.4. The differences in the sorption behaviour were further understood using molecular simulations. It was found that there was agreement between the experimental and simulation studies. Extensive equilibrium and kinetic modelling were carried out on the equilibraium and kinetic data obtained in this study. It was interesting to note that the mechanism followed in the sorption was dependent on the nature of solute as well as the size and pretreatment protocol.
