| Abstract | ||||
| This paper studies the removal of ethyl naphthalene as one of the polyaromatic hydrocarbon pollutants (PAHs) from the produced water. Magnetic super hydrophobic monolithic core-shell polystyrene (MSHMCSh@PS) was prepared using a simple and low-cost (facile in situ bulk radical polymerization) method, in the presence of 2-azobisisobutyronitrile as an initiator for ethyl naphthalene adsorption. The characterization of the MSHMCSh@PS was performed using FT-IR, TGA, SEM, TEM, and VSM. The possibility of PAHs adsorption from produced water was performed using the continuous adsorption study in a fixed-bed column. The effects of flow rate, concentration, and bed height were investigated. The results showed that the relationship between adsorption capacity with both inlet concentration and bed depth is a direct one, while the relationship between adsorption capacity and flow rate is an inverse relationship. The best column parameters were found at 2.5 ml/min flowing rate, 9 cm bed height, and 50 mg/L concentration. The experimental column results and the relationship between operating boundaries were analyzed according to Yoon-Nelson and Thomas models. The results indicated that the breakthrough curve follows the Yoon-Nelson model. The practical application results showed that the PAHs were adsorbed from the produced water using the prepared absorbent MSHMCSh@PS, which was distinguished by its superior ability. | ||||
