摘要
采用吹扫捕集-气相色谱联用,对卷烟包装材料中的苯系物、苯甲醛和苯酚10种挥发性有机物进行检测。本方法的检出限为0.011—0.98ng/cm2;空白样品的加标回收率为95%—111%;相对标准偏差在0.73%—5.33%之间;相关系数0.9991—0.9999。吹扫捕集技术作为样品的不使用有机溶剂的前处理方式,对环境不造成二次污染,具有取样量少、灵敏度高、检出限低、简便快速、结果准确等优点。
The benzene series, benzaldehyde and phenol in cigarette packing material were determined by purge ＆ trap and gas chromatography. Detection limit of this method is 0. 011-0. 98ng/cm^2,the recovery are in the range of 95% to 111% with the RSD of 0. 73%-5.33% ,and the correlation coefficients are 0. 9991-0. 9999. The benzene series,benzaldehyde and phenol can be extracted and concentrated without organic solvent to induce pollution. The method was less sample, high sensitivity, low detection limit ,operation simple and quantitative accurate.
