ADSORPTIVE REMOVAL OF MALACHITE GREEN DYE FROM AQUEOUS SOLUTION USING A NON CARBON ADSORBENT: EQUILIBRIUM, KINETICS AND THERMODYNAMICS

Abstract

In this paper, studies for the removal of malachite green dye from aqueous solution using adsorption technique are presented. There are different adsorbent available for malachite green dye removal from water effluents. Hence, the recent literature in the area is categorized according to the cost, feasibility, and availability of adsorbents. An extensive survey of the adsorbents, derived from various sources such as low-cost biological materials, waste material from industry, agricultural waste, polymers, clays, nano-materials, and magnetic materials, has been carried out. Adsorbent unsaturated polyester resin is case effective for the removal of malachite green dye from aqueous solution. The research paper studies different adsorption factors, such as pH, concentration, adsorbent dose, contact time, temperature. The fitting of the adsorption data to various models, isotherms, kinetic and thermodynamic parameter is also reported.
