Abstract
Pentachlorophenol(PCP), which is very persistent in soil and water environment, was tried to detoxify with oxidoreductive catalysts(peroxidase, laccase, tyrosinase and birnessite). To find out detoxification of PCP, the transformation of PCP through oxidative coupling was investigated in the presence of various oxidoreductive catalysts. PCP incubated with peroxidase was significantly transformed, however, in case of tyrosinase, the transformation was negligible. Using peroxidase, the optimal reaction condition was pH 5.6 and
Peroxidase, laccase, tyresinase와 같은 산화환원효소와 birnessite와 같은 무기촉매로 매개되는 oxidative coupling을 통한 PCP의 효율적인 제거 가능성을 규명하고자 하였다. 산화환원 촉매를 이용하여 PCP를 반응시켰을 경우 peroxidase로 매개되었을 때 transformation이 가장 높게 나타났고, tyrosinase로 매개된 반응에서는 거의 관찰되지 않았다 사용된 산화환원 촉매중 가장 높은 활성을 나타낸 peroxidase를 이용하여 반응조건에 따른 PCP의 transformation정도를 조사한 결과 PCP의 transformation은 pH 5.6 그리고
