Kinetic Study on COD Removal of Palm Oil Refinery Effluent by UV-Fenton

摘要

Kinetic study on COD removal from palm oil refinery effluent (PORE) has been studied by using UV-Fenton's reagent. The wastewater was collected from a refinery mill in Penang, Malaysia and treated using batch reactor with UV-lamp. The concentration of H2O2 was 2.125 g and ratio of H2O2:FeSO4·7H2O was 15:1. The results show that the reaction of the oxidation of COD in PORE by UV-Fenton's reagent is second order reaction and the reaction rate constant, k is 2.24,1.92 and 1.60 dm~3/molmin for temperature 24°C, 30°C and 40°C, respectively.
