Model smoke stream adsorption over cellulose acetate stick with three-dimensional temperature gradient by combining in-situ DRIFTS with infrared thermal imaging

Understanding the adsorption of smoke stream (SR) on cigarette filter—cellulose acetate stick with different temperatures is beneficial for controlling chemical emissions and reducing toxic effect smoking human health. However investigation corresponding properties was missing because substances cellulose sensitive three-dimensional temperature gradient. In this work, typical substances, such as CO, propylene glycol, formaldehyde, acetone, were studied by in-situ diffuse reflectance Fourier transform infrared spectroscopy assisted thermal imaging method. The capacities to these dependent time temperature. all fitted well Freundlich model. By a spectroscopic mathematical explanation, quantifying contours performed. 3D model normalized CO versus spatial coordinates established. This study gives unparalleled insight into release characteristics filtered regulatory mechanism negative
