-Remediation of oil-polluted water from waste lubricating oil by adsorption was investigated using pomegranate peels powder. Many parameters such as the oil sorption capacity, oil retention, water and oil uptake, kinetic behavior of remediation process, adsorption isotherm model, and reusability were studied. The oil sorption capacity of adsorbent was equal to 2.316 g oil /g sorbent. The sorbent has a very good retention time; it can keep 48% of the adsorbed oil after three minutes of drainage. This property makes the material a unique behavior to keep the oil for this long time. The reusability of sorbents showed a 76.2 % of the sorption capacity after 6 reusability cycles. The total amount of adsorbed oil is 11.659 g oil/ g pomegranate peels powder. The kinetic study showed that the rate of adsorption followed the first order kinetics. Langmuir, Frendlich adsorption isotherm models were applied to check if any of these models is fitting the adsorption remediation process.
