摘要
为准确测定卷烟烟气中对-甲酚和间-甲酚异构体,进行了流动相中添加β-环糊精(β-CD)前后用反相高效液相色谱法分离检测卷烟烟气中7种有害酚的比较试验。结果表明:①流动相中添加5.29×10-3mol/Lβ-CD水溶液,可同时将对-甲酚、间-甲酚、邻-苯二酚、间-苯二酚、对-苯二酚、苯酚和邻-甲酚分离;②7种酚的回收率为92.9%～102.4%,RSD1.78%～4.33%。该法可用于卷烟烟气中这7种有害酚的测定。
In order to determine p - cresol and m - cresol isomers in cigarette smoke, the comparison experiments on the separation and detection of seven harmful phenols in cigarette smoke by reversed-phase high performance liquid chromatography were performed before and after that β-eyclodextrin（ β-CD） was added into the mobile phase. The results indicated that ： 1 ） when the concentration of β- CD in aqueous solution was 5.29 ×10^-3 mol/L, the target analytes, p- cresol, m- cresol, catechol, resorcinol, hydroquinone, phenol, and o - cresol, were completely separated; 2） the recoveries of the seven phenols ranged from 92.9% to 102.4% with the RSDs of 1.78% to 4.33%.
