Abstract
This paper investigates the ability of Bottom ash to adsorb three cationic dyes from aqueous solution in single and tertiary systems. Crystal Violet (CV), Methylene Blue (MB) and Malachite Green (MG) were used as cationic dye models. The surface characteristics of Bottom ash were investigated using Fourier Transform Infrared (FTIR). Pseudo second order model was fitted better than Pseudo First order
model for all system of MG, MB and CV. From the isotherm study, the adsorption capacity increased in the order of MB< MG
