Abstract

Advanced Oxidation Process (AOP) is commonly known as one of the chemical treatment designed specifically to remove unwanted materials or waste, either in the form of organic or inorganic materials. This technology is commonly being utilized in the waste water treatment industry by performing complex oxidation reactions in order to breakdown the biologically toxic materials. Basically, this project will be conducted based on a specific method of advanced oxidation process (AOP) namely Fenton’s oxidation with the aid of photolysis on one of the rare amine wastes, Diisopropanolamine (DIPA) based on different light intensities as the experimental parameters. The major motivation for the author to perform this study is to find out the effect of degradation efficiency of DIPA under different light radiation. The author has constructed a simple experiment setup for Photo-Fenton oxidation process with light radiation available where the reaction system will be placed directly under the light source. Standard solutions for each reagent were also prepared with proper procedures by the author. Prior to the experiments, the author has produced a calibration curve for concentration estimation of the processed samples. Degradation efficiency is mainly determined by Chemical Oxygen Demand (COD) by utilizing COD digester and Hach® DR 5000. Experimental work started with optimization of hydrogen peroxide (H2O2) under both light sources, 1.0 M of hydrogen peroxide gave the highest COD removal in percentage instead of 0.01 M and 0.1 M in both cases. Then, optimization of DIPA concentration is carried out for both light intensities. 300 ppm of DIPA solution became the most optimum concentration for 500 Watt environment; whereas 500 ppm for 300 Watt light radiation. The most optimum systems were compared for the most efficient light intensity for DIPA degradation under Photo-Fenton oxidation. 300 Watt light source gives the highest COD removal percentage of 60.64% and said to be the higher efficiency light condition for such oxidation process.
