| Abstract: |
| The degradation effects and mechanism of 1,2,4-Trichlorobenzene（1,2,4-TCB） in Selenastrum carpricornutum were discussed in this paper. The results showed that the degradation abilities differs with initial 1,2,4-TCB concentrations. The highest degradation rate was 52.8% occurs at 1.0 mg·L-1, and the half life of degradation was 6.62 d. The growth of Selenastrum carpricornutum was inhibited when initial concentration of 1,2,4-TCB was above 5 mg·L-1, but the growth ability of Selenastrum carpricornutum was recovered when the alga lived through the adaptive phase. Further determination with GC-MS analysis technique showed that the major degradation pathway of 1,2,4-TCB was the replacement of chloric substituent by other active groups. |
