| Abstract | : | Waste of heavy oil contains a number of substances that can pollute the air, soil and water. Waste of heavy oil may contain metals, chlorine solutions, and other pollutants. One litre of waste heavy oil can damage millions of litres of fresh water from water sources in the soil. If waste of heavy oil spills on the ground it will affect ground water and will be harmful to the environment. This is because heavy oil waste can cause arid soil and loss of nutrients. While waste of heavy oil which cannot be dissolved in water can also endanger water habitat. Waste of lubricating oil is included in B3 waste which is flammable and explosive so that if it is not handled by its management and disposal, it will endanger humans and the environment. So to overcome this problem, it needs to find an effective and efficient method for removing waste of heavy oil from the waters. Fe3O4@(CTAB-montmorillonite) is one of the materials that can be used to reduce oil waste from waters. This research was conducted to determine the mechanism that occurs in the process of adsorption of waste of heavy oil on the Fe3O4@(CTABmontmorillonite) adsorbent, using an isotherm model and an appropriate adsorption kinetics. The research was carried out in a laboratory scale using an artificial solution of heavy oil waste and then mixing Fe3O4@(CTAB-montmorillonite) adsorbent. So that the results obtained for adsorption of heavy oil waste on adsorbent are more in accordance with Freundlich model, with R2 value is 0.997 and the corresponding kinetics model is pseudo second order kinetics with R2 value is 0.997 and k is 3.314 × 10-4 g/mg/minute |
