Studies on removal of AS(III) by adsorption on flyash and activated carbon powder have been carried out at room temperature (30 +/- 1 degrees C). The adsorption isotherm of AS(III) on flyash and activated carbon powder was obtained in a batch reactor. Various parameters such as pH, initial concentraction of adsorbate and absorbent dose were studied. The experimental adsorption data fitted reasonably well to the Langmuir and Freunlich isotherms for both the adsorbents. Activated carbon has been observed to have greater adsorptive capacity than flyash.
