Abstract
The adsorption of two acid dyes, viz. Acid Red AR114 and Acid Blue AB25, on to bagasse pith, a waste material from the sugar cane industry, has been studied. Equilibrium isotherms and agitated batch contact time studies have been carried out. A mass-transfer model has been used based on a Langmuir-type isotherm at maximum saturation. This simple or pseudo-irreversible isotherm and the assumption of pore diffusion enables a pore diffusion mass-transfer model to theoretically predict the experimental concentration decay curves very rapidly.
