摘要：
Rice Husk Ash, a waste from rice mills has been used as an adsorbent for the removal of chemical oxygen demand from aqueous solutions of textile dyes. The adsorption capacity of rice husk ash for five aqueous acid dye solutions has been determined by adsorption isotherm. The adsorption data have been fitted to Freundlich isotherm and Langmuir isotherm by the least square method and the values of the constants k, n, C-m and b have been obtained. The effect of contact time, pH, adsorbent concentrations and rate constants for each dye have been calculated.
