Isopropyl alcohol (IPA) is the major organic ingredient in wastewater of semiconductor manufacturing industry. The efficiency of traditional wastewater treatment processes using physical-chemical or microorganism decomposition approaches is limited. Wastewater containing organic solvents that are not decomposed deteriorates the quality of water in the environment, while its volatile nature results in air pollution that affects the health of factory workers and residents in the neighborhood. Hence, it is of urgent need to develop more efficient pollution reduction technology. In this study, gamma-rays were induced using a Co-60 radiation source to treat IPA alone or in combination with hydrogen peroxide. Experimental results reveal that the combined g-ray/H sub(2)O sub(2) process shows better decomposition efficiencies than the use of g-ray or H sub(2)O sub(2) alone.
