Anthracene removal from water onto activated carbon derived from vehicular tyre

ABSTRACT

The present study focuses on adsorptive removal of anthracene by application of activated carbon developed from waste vehicular tyres (VTAC). Different experimental parameters were varied to examine their influence on anthracene adsorption. The results reveal that concentration of anthracene in aqueous phase reduces continuously with enhancement in shaking time. After a period of 75 min, the adsorption of anthracene on VTAC was observed to be in equilibrium. The adsorption of anthracene was >99% in presence of 14–20 mg and an adsorbent dose of 8 mg was used to analyse the effect of other parameters in the present study. As pH of solution is lowered, rise in adsorption capacity of VTAC was observed. The obtained data were applied to Langmuir and Freundlich isotherms for studied PAH adsorption. The second order kinetics was suggested to be better fitted with R² values >0.95. Intra-particle diffusion and Boyd-Reichenberg model were applied for investigating the mechanism of adsorption.
