摘　　要：用气相色谱法分离,氢焰离子化检测器测定了乙醇-对甲酚混合介质中的对羟基苯甲醛(PHB),标准加入回收率在92.6％～111％。对实际样品进行了测定,与其他方法结果相符;对于PHB含量为10.85％的试样测定8次,计算其RSD为9.8％。p-hydroxybenzaldehyde (PHB) was separated from the mixed medium by GC and determined with a hydrogen flame ionization detector. A recovery of 92. 6%-111% was achieved. The method has been applied to the analysis of real samples, the results obtained were in close agreement with other methods. The RSD(n = 8) for a sample containing 10. 85% PHB was 9.8%.
