Removal of Malachite Green dye by adsorption using char

Abstract

The objective of this project work is to study the adsorption of Malachite Green dye using char. Cheap and eco-friendly adsorbent has been used for removal of malachite green dye from aqueous solution. Liquid phase batch operations were carried out to observe the effect of various experimental parameters such as contact time, temperature, pH, initial concentration of malachite green and adsorbate dose and the optimum conditions for these parameters were evaluated. Various characteristics of char made out of Sheesham seeds were examined. Study on adsorption kinetic and adsorption isotherm was carried out and best fitting models for rate kinetics and isotherms were suggested. Comparisons with other available low cost adsorbents were also done. This project work can help in designing low cost adsorption columns for treating effluent water in industries or other adsorption processes.
