A study on the efficiency of PEG as additive for phenol removal from waste water using tamarind shell ash as adsorbent

Seema Roopesh, Merlin Thomas, J.V.Patel

The potential of polyethylene glycol (PEG) of molecular weight 2000 as additive for phenol adsorption from aqueous solution using tamarind shell ash was studied. Batch studies were carried out under varying conditions of contact time, adsorbent dose and pH for samples with and without PEG. The results showed that for all the process conditions studied, the addition of PEG enhances the removal of phenol from its aqueous solution. The amount of adsorption was found to decrease with pH and increase with contact time and adsorbent dose.
