摘　　要：针对卷烟烟气p H值测定提出了烟气萃取液缓冲当量的概念,并从缓冲当量的角度论述和验证了水作为萃取体系检测卷烟烟气酸碱性的合理性,建立了检测卷烟主流烟气粒相物酸碱性的评价方法.采用剑桥滤片收集卷烟主流烟气粒相物,用添加了2 mmol/L KCl的去离子水萃取滤片,p H复合电极测定萃取溶液的p H值.结果表明采用水萃取卷烟烟气粒相物来评价卷烟烟气的酸碱性可行.The concept of buffer capacity of cigarette mainstream smoke condensate was put forward according to the determination of p H values of cigarette smoke. The reasonability of using water as the extraction system was discussed and verified through the buffer capacity. An evaluation method of p H values of cigarette smoke was established. The mainstream cigarette smoke was collected by a Cambridge pad,extracted using a 2 mmol / L KCl aqueous solution,and then determined with a p H combination electrode. Our results showed that determining p H values of the mainstream cigarette smoke using water as the extraction system is both appropriate and applicable.
