영문 초록

The objective of this study was to investigate the destruction efficiency and to determine the fundamental parameters of oxidation kinetics under the supercritical water(SCW) condition. Target material was cephradine, toxic and antibiotic material, in the pharmaceutical wastewater. For this purpose, the effect of reaction temperature and oxidant were investigated on the destruction efficiency of cephradine. And the oxidation kinetics of cephradine was derived by using a empirical power-law model. The experiment was carried out in a cylindrical batch reactor made of Hastelloy C-276 which was endurable high temperature and pressure. The destruction efficiency of cephradine increased with increment of the temperature and reaction time. Also the type of oxidants was effected and oxidants(Air and H2O2) were enhanced the destruction efficiency. The global oxidation kinetics for cephradine has led to two rate expressions according to type of oxidant. - In the presence of air oxidant : Rate = k · e-Ea/RT[Ceph.]1.0[O2]0.51?.05(k=3.27?05/sec. Ea = 63.25 kJ/mole) - In the presence of H2O2 oxidant : Rate = k · e-Ea/RT[Ceph.]1.0[H2O2]0.62?.02(k=2.76?04/sec. Ea = 47.65 kJ/mole)
