| 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 |
