Abstract
수용액에 함유되어 있는 페놀을 peroxidase 및 H2O2를 이용하여 침전시킨 후 금속이온을 첨가하여 효과적으로 침강시킬 수 있는 방법에 대하여 연구하였다. Peroxidase와 H2O2에 의한 반응 및 원심분리에 의해서 수용액 속의 페놀을 80% 이상 제거할 수 있었다. 또한 효소반응 후 금속이온(Al3+, Fe2+, Fe3+, Cu2+)을 첨가하면 효소반응에 의하여 생성된 페놀침전물의 침강효율을 증가시킬 수 있었다. 페놀침전물의 침강효율은, pH7 수용액에서 0.1mM 이상의 Fe3+ 이온을 첨가할 경우 가장 우수하였다.
The use of metal ions was studied for the efficient sedimentation of phenolic precipitates which were formed by peroxidase and H2O2 in aqueous solutions. Over 80% of phenol was removed from aqueous solutions by enzyme reactions using peroxidase and H2O2 followed by centrifugation. Adding metal ions, Al3+, Fe2+, Fe3+, Cu2+ to a solution containing phenolic precipitates increased the sedimentation efficiency of the phenolic precipitates. The use of Fe3+ ion over 0.1mM was most effective for the sedimentation of the phenolic precipitates.
