Kapok Hull indegeneous agricultural waste by sulphuric acid treatment was converted to a carbonaceous sorbent and it is tested for efficiency in removing acid dye. Batch kinetic and isotherm experiments were conducted to determine the sorption of the acid red from aqueous solution with activated carbon. The factors affecting the rate of adsorption processes depends on initial dye concentration, agitation time, carbon dose, particle size and temperature. The adsorption process followed first order rate kinetics. From the intra-particle diffusion rate equation, adsorption rate constant, diffusion rate constant and diffusion coefficient are determined. The structure and morphology of activated carbon was characterized by XRD and SEM studies respectively.
