Abstract

Suspected carcinogen, TCE and PCE, are the most common groundwater pollutants extensively used as a solvent and degreaser. In this study, oxygenases were immobilized in Ca-alginate and chitosan bead. TCE degradation by the immoblized enzyme beads were measured for various size, enzyme addition volume and TCE contact time. The degradation was decreased as increasing the bead size. For overnight , more than 20% of TCE was degraded. The variation of enzyme activity was tested for the repeated use of enzyme beads.
