为研究柠檬酸钾对主流烟气中稠环芳烃的选择性降低效果,采用湿法添加将不同量的柠檬酸钾溶液加到烟丝中,研究了不同添加量对焦油和烟气中稠环芳烃(PAHs)的影响.结果表明:①柠檬酸钾添加量在2‰～15‰范围内,随着添加量的增加,焦油含量呈下降趋势;②苯并[α]蒽、、苯并[α]芘的含量随着添加量的增加而减少,当柠檬酸钾添加量为8‰时,3种稠环芳烃的含量达到最低值,降低率分别达到25.89%,29.71%,23.76%,随后随着添加量增加,含量也增加.

In order to study on effect of selective reduction of polycyclic aromatic hydrocarbons (PAHs) on mainstream smoke by potassium citrate,different amount of potassium citrate solution were added to cut tobacco through wet adding,and the effects of addition on PAHs were studied.The results showed that:①when the addition was in the range of 2‰～15‰,with the increase of potassium citrate improver amount,the content of tar deliveries per cigarette decreased;②With the added amount of potassium citrate increases,benzo[α] ant-hracene,benzo [α]pyrene,chrysene content decrease when the potassium citrate adding amount of 8‰,the three kinds of PAHs content reaches a minimum value,the reducing rate were 25.89%,29.71%,23.76%,respectively,and then as the adding amount increase the three kinds of PAHs contents also increased.
