Abstract: Chlorinated cathechols are formed during the chlorination stage of bleaching plant which are toxic. Removal of tetrachlorocatechol by adsorption using bagasse fly ash (BFA), rice husk fly ash (RHFA) and activated carbon (AC) has been investigated. The practical applicability of these adsorbents has been studied in batch operations and effect of various parameters such as initial concentrations of tetrachlorocatechol, adsorbent dose, pH of the solutions have been investigated. The removal kinetics of tetrachlorocatechol shows first order expression and equilibrium adsorption data suited well for both Langmuir and Freundlich isotherms. BFA and RHFA with the AC reveals that use of these adsorbents will be economically viable.
