| 摘 要： | 建立了萃取溶剂、固相萃取小柱净化、高效液相色谱( HPLC)法检测烟草及烟草制品中马来酰肼(MH)残留量的方法,并采用该方法检测了23个烟草样品中的马来酰肼残留.结果表明:①用4 mol/L盐酸加热回流萃取1h效果较好；②用Varian Microsorb- MV 100-5 C18色谱柱,以0.1 mol/L醋酸水溶液为流动相,等梯度洗脱,流速0.7 mL/min,检测波长313 nm,20 min内MH色谱峰和杂质色谱峰可以有效分离；③该法的回收率为97.11％,相对标准偏差为7.13％.该方法适合烟草及烟草制品中马来酰肼的测定.

| Abstract: | A method for the determination of maleic hydrazide(MH)in tobacco and tobacco products was established,in which MH in tobacco sample was extracted with a solvent,and cleaned up by a solid phase extraction cartridge,then detected with high performance liquid chromatography.The residue of MH in 23 tobacco samples was determined.The results showed that: 1)Good results were obtainable when tobacco sample was extracted with 4 mol/L hydrochloric acid under heating and refluxing for 1 hour.2)The MH peak was complet... |
