Abstract: The kinetics study of removal of acidic, basic and disperse dyes on sawdust, polymerized sawdust and sawdust carbon were carried out by adsorption technique. The factors affecting the rate processes involved in the removal of different dyes e.g. initial dye concentration, agitation speed, mass of adsorbent, temperature, have been studied. The adsorption process followed first order rate kinetics. The adsorption data generally fit the Lagergren equation and the intraparticle diffusion rate equation from which adsorption rate constants, diffusion rate constants and diffusion coefficients were determined. Intraparticle diffusion was found to be the rate-limiting step. These kinetic parameters were compared for various dyes under different conditions
