摘　　要：以玉米多孔淀粉(PS)和交联磷酸玉米多孔淀粉(PPS)为材料,研究了不同水解时间制得的玉米多孔淀粉和不同取代度交联磷酸玉米多孔淀粉对卷烟主流烟气气相物中HCN、NH3、巴豆醛的清除效果。借助于扫描电镜(SEM)和全自动气体吸附仪(ASAP)确定了多孔淀粉最佳吸附HCN、NH3、巴豆醛孔结构参数。通过连续流动法,离子色谱法和高效液相色谱法分别对HCN、NH3、巴豆醛进行检测,结果表明当水解反应时间4 h玉米多孔淀粉和交联磷酸玉米多孔淀粉(DS=0.092)对HCN、NH3、巴豆醛清除效果最好。玉米多孔淀粉对烟气中HCN、NH3、巴豆醛质量分数分别降低5.922%、24.278%和20.843%。交联磷酸玉米多孔淀粉对烟气中HCN、NH3、巴豆醛质量分数分别降低13.041%、35.925%、31.062%。This article uses corn porous starch（PS） and crosslinking phosphoric acid corn porous starch（PPS） as materials. It studies the effects of PS obtained in different hydrolysis time and different PPSs with different substitu- tion degrees （DS） for the mainstream of cigarette smoke vapour phase compounds to the elimination of HCN, NH3 and crotonaldehyde. With the help of SEM and ASAP, It confirms that the best parameter of pore structure to abosorb HCN, NH3 and crotonaldehyde for starch. Using chromatography of ions and high performance liquid chromatography respectively tests HCN, NH3 and crotonaldehyde through continuous flow methods. The results indicates that PS and PPS （ DS = 0. 092） have the optimal adsorption effects on HCN, NH3, and crotonaldehyde when the hydrolysis time is 4 h. PS can reduce HCN, NH3 and crotonaldehyde by 5. 922%, 24. 278%, 20. 843%, respectively. PPS can reduce HCN, NH3 and crotonaldehyde by 13. 041% ,35. 925% ,31. 062%, respectively.
