| Abstract:In order to study the effect of potassium and sodium content on the thermal analysis parameters of cigarette paper and the routine components in mainstream cigarette smoke, seven kinds of cigarette papers with different potassium and sodium content were analyzed by TG/DSC in oxidizing atmosphere，and thermal analysis parameters at different weight lossing stages were obtained. At the same time, the routine components in mainstream smoke of the cigarettes were made from the above cigarette paper were measured. The results showed that the weight lossing processes of the cigarette papers could be subdivided into four distinct stages, i.e. the loss of adsorbed water, the thermal oxidative degradation of the cellulose, the combustion of coke and the decomposition of calcium carbonate. Within the range of 0.74%~1.99% citrate ion and 0.38%~0.99% potassium and sodium ions, the change of potassium and sodium ions content in cigarette paper had no obvious effect on moisture in mainstream smoke, but the increase of their content could lead to the decrease of TPM（total particle material）, nicotine, tar and CO by about 0.91、 0.14、 1.0 and 1.7 mg/cigarette, respectively. |
