Improving the quality of palm oil liquid waste using nanocomposite TiO2/EPB activated carbon through adsorption-photodegradation

Abstract


Abstract. Research has been carried out on the use of nanocomposite of TiO2/activated carbon in reducing the quality parameters of palm oil liquid waste through the adsorption-photodegradation mechanism with DO (dissolved oxygen) parameters. Characterization of samples catalyst nanocomposite of TiO2 /activated carbon was used using Scanning Electron Microscopy (SEM-EDX) and DO parameters with variations in the mass percentage ratio of TiO2/activated carbon are namely (0.4:0.3), (0.6:0.4), (0.5:0.5), (0.4:0.6), and (0.7:0.3). SEM-EDX shows that TiO2 particles stick and spread unevenly on the surface of the activated carbon, and the ratio of the atomic mass of titanium to sample abundance is 0.25. Based on the analysis of DO of palm oil liquid waste using catalyst nanocomposite of TiO2 /activated carbon, it is known that the DO value of palm oil liquid waste increases with the increase in contact time of the TiO2/activated carbon sample with sunlight. This indicates that TiO2/activated carbon can degrade the presence of hazardous chemicals in palm oil liquid waste through the adsorption-photodegradation mechanism.
