| Abstract: | A high-performance liquid chromatography(HPLC) method for the determination of acrolein in cigarette smoke has been developed,and the trapping method of acrolein improved.By using the DNPH-treated Cambridge filter to collect the acrolein in cigarette smoke,the reaction condition of splitting acrolein with 2,4-Dinitrophenylhydrazine(DNPH) in the filter was investigated.The results show that this established method has had high sensitivity and good selectivity compared with other analytical methods,and this simple and efficient method can be expected to have a wide application. |
