Sustainable Motor Oil Recycling Process using Banana Peel (Musa Paradisiaca) for Fe ion Adsorption

Abstract

Due to the inadequate disposal of materials containing potentially toxic elements, the concern with the preservation of the environment has increased. Biosolvent materials have been used as an alternative material to treat waste. The objective of this paper was to test the efficiency of banana peel (musa paradisiaca) for the adsorption of Fe ions present in spent motor oils. The banana peels were dried, crushed and sieved (16 mesh). The oil used was collected from the disposal tanks in gas stations in the city of Uberaba, Minas Gerais State, Brazil. The analyses were carried out in batch mode, under agitation, to guarantee contact between the adsorbent and the oil. After contact, oil and adsorbent were separated by centrifugation or by vacuum filtered. The process of liquid-solid separation by centrifugation influenced the results due to the action of the centripetal force causing the separation of the ions by drag but resulted in a removal efficiency of 33.43 to 94.53% of Fe iron removal from the oil, depending on the treatment time. Using vacuum filtration, the process had an efficiency of 38.58%.
