| Abstract |
| Phenol compounds in wastewater is difficulty in treatment because of higher salinity, acidity, COD and non-biodegradable properties. So there is limitation to control phenol wastewater using the so far conventional process. An alternative method of treating such wastewater is Advanced oxidation processes(AOPs). Ozone(O3) process can easily destroy the phenol compounds using its highly reactivity with free radicals, especially hydroxyl radicals. In this study, magnetite was developed as an ozonation assistance material for the degradation of phenol in water. Magnetite NPs have attracted widespread attention as their unique properties, such as high surface area, chemical reactivity, the nearly full polarization, inexpensive and supermagnetisim so that magnetite is easily separated and recovered. In order to evaluate the adsorption on magnetite, experiments were performed in two different ways(single ozonation, Ozonation/Magnetite). 10 g/L of magnetite and 200 mg/L-phenol(C0: 511.21 mg/L) water was mixed generating the ozone(1g/hr). After 3 hr, phenol removal was 100% and COD removal was 84.35%. The degradation efficiency of phenol and COD increased about each 28.84, 34.10% due to the adsorption of magnetite. |
