Abstract

Used motor oil dumped in water sources is one of the factors that cause water pollution in our environment Therefore, this study aimed to increase the solubility of motor oil by using nonionic surfactant, Brij 35 and the biodegradability of used motor oil by Pseudomonas aeroginoso. The fresh motor oil was used in this experiment as comparison with used motor oil. The results showed that the best eoncentration of Brij 35 to remove used of motor oil is at concentration of 0.00008 M and mixing speed at 250 rpm with percentage efficiency 6.79"10 compared to 3.83% at 150 rpm mixing speed. The removal of used motor oil was supported by the FTIR analysis data. In the biodegradability test, there were emulsions formed thus, indicated that the used motor oil was successfully degraded
