摘　　要：建立了一种测定热塑性酚醛树脂中游离苯酚的反相高效液相色谱法 .采用YWGC18(5 0mmi d × 2 5 0mm ,10 μm)色谱柱 ,以甲醇 水 (体积比为 4 5∶5 5 )作流动相 ,流速为 1 0mL/min ,紫外检测波长为 2 16nm ,灵敏度为0 0 4AUFS .在 2 2 0 4～ 4 4 0 8mg/L的范围内 ,苯酚的峰面积Y与其质量浓度X的线性关系良好 ,回归方程为Y =195 0 3X +2 75 6 8(r=0 9998) .苯酚的加标回收试验的平均回收率为 99 5 % ,RSD为 1 4 % ,苯酚的最小检出量为0 8ng .与其他方法相比 ,该方法具有操作简便、线性范围广、检出限低和回收率高等特点 。A method using reverse phase high peformance liguid chrometography(HPLC) for the determination of phenol in phenolic resin is described. Chromatographic analysis was carried out on a YWG C 18 column (5 0 mm i. d.× 250 mm, 10 μm) with methanol water (45∶55, V/V) as mobile phase, with a flow rate of 1.0 mL/min and UV detection wavelength at 216 nm. The sample of phenolic resin was dissolved in methanol. Under those optimum conditions mentioned above, the linear regression equation was Y =1 950 3 X +2 756 8( r =0 999 8), the linear range was 2 204 440 8 mg/L. The average recovery of phenol was 99.5% and the relative standard deviation was 1 4%. The method is simple,fast,sensitive and accurate.
