In this research, adsorption malachite green (MG) using Sugarcane bagasse (SB) and Rice husk (RH) were studied by batch method. Factors influencing dye adsorption such as the initial dye concentration, sorbent dosage, exposure time, temperature effect and pH, were investigated. The Langmuir, Freundich Temkin and Dubinin–Radushkevich (D-R) isotherms were used to fit the equilibrium data, and the results showed that the Freundlich and Langmuir model provided the best correlation of the

It was observed that the pseudo-second-order kinetic equation could explain the biosorption kinetics of dye on both adsorbents and intra particle diffusion showed that dye adsorption was controlled by multi-adsorption stages with bagasse surface area. The results showed that both of them can be an economical sorbent for removal of dye from aqueous systems.
