The indigenous microorganisms existed in the contaminated soil could degrade low concentration of chlorophenol 00mgg^(-1, however, their degradative capacity was limited when chlorophenol concentration was high about 500mgg^(-1, which may be caused by the toxic effect of high concentration of chlorophenol on the indigenous bacteria.

土壤中存在的土著的氯酚降解菌可以对低含量的氯酚100mgg^(-1进行降解；但是当土壤中氯酚含量较高500mgg^(-1时，土著微生物的降解能力受到限制，这可能是高浓度的氯酚对土著的氯酚降解菌会产生毒性作用。

In the detection experiments, the scan rate is set at 0.3 V/s under the analysis of linear sweep voltammetry. On the cyclic voltammetry plot, each pair of clear redox peaks was observed for 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), and penta- chlorophenol. The potentials of the redox pairs were 1.218 and -0.460 V for 4-CP, 1.128 and -0.448 V for 2,4-DCP, and 1.037 and -0.473 V for PCP.
