Abstract
Cigarette smoke contains many chemicals including nicotine which is harmful and can cause health problems such as carcinogenesis disease cardiovascular respiratory renal and reproductive systems. Removal of nicotine from mainstream smoke can be done through adsorption with filters or solid adsorbents. In this study we explored the use of activated carbons for the removal of nicotine from cigarette mainstream smoke. Activated carbons were prepared from dried hemp (Cannabis sativa) stem at an activation temperature of 350�0�C using phosphoric acid as an activating agent. The results showed that the activated carbons with variable surface functional groups and porosity exhibited high efficiency for nicotine adsorption removing 68�% of nicotine from cigarette mainstream smoke. Through X-ray photoelectron spectroscopy and temperature-programmed desorption analyses we identified that oxygen-containing functional groups particularly carboxylic groups exhibited a superior ability to adsorb nicotine. The computational analysis with DFT simulations further supported the importance of oxygen-containing surface functional groups in facilitating nicotine adsorption with the carboxylic group providing the lowest adsorption energy among other functional groups. ? 2023 Springer Nature Limited.
