摘要
采用Tenax-TA吸附—热脱附—气相色谱法测定空气中的苯酚和甲酚。苯酚和甲酚异构体在液晶PBOB填充柱上分离良好。方法平均回收率为85.5％～92.2％;相对标准偏差为3.2％～5.4％;采样体积为1L时,各酚最低检出浓度为3μg/m^3。测定了几种炼油厂废气中苯酚和甲酚的浓度。
Using Tenax-TA thermal desorption-packed column gas chromatography for determination of phenol and cresols in air has been conducted. Phenol and cresol isomers could be well separated in liquid crystal PBOB packed column. The average recovery rates were 85.5%- 92.2%, and the relative standard deviation ranged from 3.2% to 5.4%. The minimum detection level for one litre air sample was 3μg/m3.
