Statistical Effect Of Activation Condition for Heterogeneous Fenton Catalyst Derived From Jackfruit Peel Waste on Pentachlorophenol Removal in Water

Abstract

Application of heterogeneous Fenton catalyst based activated carbon derived from biomass for persistent organic pollutant’s removal in wastewater has been considered a promising treatment approach toward circular economy and environmental protection. However, statistical evaluation on preparation conditions for a catalyst derived from jackfruit peel applied for Pentachlorophenol (PCP) degradation in water has not been investigated yet. This study investigated statistically single and the combined effect of temperature and ratio between iron and activated carbon produced from jackfruit peel (Fe/JAC) on capability of PCP degradation in water. Physio-chemical characteristics of Fe/JAC catalyst including surface morphology, crystal structure, element contribution and surface functional groups were analyzed with methods of Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Energy Dispersive X-ray Spectroscopy (EDS) and Fourier Transform Infrared Spectroscopy (FTIR), respectively. The results revealed that synergetic and quadratic effects of temperature and Fe/JAC ratio were statistical contributors on the PCP degradation in water. The results of the quadratic model indicated effective degradation of PCP in water when temperature and Fe/JAC ratio were from 298℃ to 500 and 12.4 to 20.0%, respectively. The Fenton catalytic properties for PCP decomposition in the best conditions of 20%Fe/JAC at 500℃ has large pores with the active sites of Fe₂O₃ with size ranged from 500 to 700 nm and oxygen functional groups.
