The study of low-cost (non-convectional) adsorbents, bone char, clay, limestone/clay mixture and silical gel to remove aromatic from DPK have been investigated. Effect of contact time, Adsorbent mass, pH and temperature on the rate of percentage aromatic removal was determined. Equilibrium studies showed that oxidized bone has the highest adsorption capacity. Analysis of variance (one-way) and multiple regression was used to rank the adsorbent in the order of highest selectivity for aromatics as follows: oxidized bone, carbonized bone, activated clay, Silica gel, limestone/clay and limestone. The results from this study can provide a basis for the understanding of adsorbate sorption mechanism.
