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