Abstract

Ozonation was performed under various experimental conditions that $Al_2O_3$ catalysts dosage and temperature for removal of DMP in laboratory scale batch reactor. Flow rate of ozone $1.0Lmin^{-1}$ and ozone concentration of $300{\pm}10mgL^{-1}$ were maintained constantly, and the pH, $COD_{Cr}$ and TOC was measured in 10 min intervals during the 60 min at oxidation processes. As a result, the presence of the $Al_2O_3$ than only ozonation increased the removal efficiency of both $COD_{Cr}$ and TOC in solution. The pseudo first-order rate constants for the elimination of $COD_{Cr}$ and TOC were $3.65{\times}10^{-4}sec^{-1}$, $2.52{\times}10^{-4}sec^{-1}$, and activation energy was $0.75kcal{\cdot}mol^{-1}$ and $0.70kcal{\cdot}mol^{-1}$ at $20^{\circ}C$, respectively.

실험실적 규모의 순환형 회분식 반응기에서 Dimethyl phthalate (DMP)성분을 효율적으로 제거하기 위하여 $Al_2O_3$촉매의 주입 그리고 반응온도의 조건을 달리하여 오존산화 반응을 수행하였다. 산화 반응에서 오존의 유량은 $1.0Lmin^{-1}$, 오존 농도를 $300{\pm}10mgL^{-1}$로 일정하게 유지 하였으며, 산화 반응이 진행되는 60분 동안 10분 간격으로 pH, $COD_{Cr}$와 TOC를 측정하여 이를 비교 분석하였다. $O_3/Al_2O_3$에서는 $O_3$ 단독 공정에 비해 $COD_{Cr}$ 및 TOC 측정값에 기초한 제거효율은 증가하였으며, $20^{\circ}C$에서 $COD_{Cr}$ 및 TOC의 반응속도상수는 $3.65{\times}10^{-4}sec^{-1}$, $2.52{\times}10^{-4}sec^{-1}$, 활성화 에너지는 $0.75kcal{\cdot}mol^{-1}$, $0.70kcal{\cdot}mol^{-1}$로 각각 나타났다.
