- W3139280158 abstract "Palm oil mill secondary effluent (POMSE) has a high color intensity, dissolve oxygen, turbidity, and an organic load of BOD which still not achieved the discharged requirement by the Department of Environment (DOE) and led to detrimental to the aquatic life. The photocatalytic degradation process is one of the promising methods in wastewater treatment due to its advantages. However, the study on POMSE treatment using the photocatalytic degradation process in the presence of ZnO-PEG nanoparticles (NPs) is still limited. Therefore, this study reports on the photocatalytic degradation of POMSE by using ZnO-PEG NPs. The ZnO-PEG NPs was characterized by using XRD and FTIR where the results show that there are no impurities present in the samples and presenting the nature and chemical bonds of ZnO-PEG 30nanoparticle. Then, the optimization of the photocatalytic degradation of POMSE in a UV-activated ZnO system based on central composite design (CCD) in response surface methodology (RSM) was determined. ZnO-PEG NPs have a great potential in degradation of POMSE and this is supported with the results obtained from the experimental works. Three potential factors which are initial pH of POMSE (A), Loading of ZnO-PEG (B), and concentration of POMSE (C) were evaluated for the significance design of experiment. It is found that all the three main factors were significant, with contributions of 34.5% (A), 79% (B), and 82% (C) respectively, to the POMSE degradation. Accordingly, the optimum condition for the photocatalysis degradation process of POMSE is under pH 6.5 in presence of ZnO-PEG with 0.08 g/L for the 25% of POMSE concentration. Then, the photocatalytic activity mechanism of ZnO-PEG nanoparticle was studied by using the kinetic study. It is believed that this integrated approach can be implemented in the industry to achieve discharged standard of POMSE and maintain the green environment for future generation." @default.
