摘　　要： 利用气相色谱-质谱联机、高效液相色谱等分析方法,探讨了氟苯酚好氧生物降解历程;研究了不同pH值对间氟苯酚羟基化产物的影响.结果表明,氟苯酚好氧生物降解主要产生邻位羟基化中间产物.随着pH值升高,C2邻位羟基化产物(3-氟-1,2-邻苯二酚)与C6邻位羟基化产物(3-氟-1,6-邻苯二酚)的比值逐渐增加,pH7.5时检测不到C6邻位羟基化产物(3-氟-1,6-邻苯二酚). With gas chromatography-mass spectrometry, high performance liquid chromatography analytic methods, it was proved that the ortho-hydroxylation medial product was produced mainly from the aerobic biodegradation of fluorophenols. The influence of different pH value on the ortho-hydroxylation products was studied. With increasing of pH value the ratio of C2 ortho-hydroxylafion to C6 ortho-hydroxylation increased gradually; and no C6 ortho-hydroxylation was examined and measured at pH 7.5.
