The adsorption of Scutellariae radix carbonisata-derived nano-components on harmful substances in mainstream cigarette smoke

Research into new filter tip materials capable of adsorbing harmful substances in cigarette smoke has long been a focus of the industry. In this study, Scutellaria baicalensis carbon nanocomponents (SRC-NCs) were prepared using Scutellaria baicalensis as the carbon source. The particle size was approximately 10–24 nm. The carbon spheres, mainly composed of carbon, had active groups such as hydroxyl and carboxyl on their surfaces and had good water solubility and lipid solubility. SRC-NCs can effectively adsorb various compounds in mainstream smoke, particularly benzo[a]pyrene, exhibiting adsorption performance superior to that of activated carbon and cellulose acetate—a commonly used material in cigarette filters. It holds promise as a potential substitute for cellulose acetate.
