Preparation and adsorption properties of chitosan/polyaniline-GO nicotine molecule-imprinted composites
Chitosan(CS)/polyaniline(PANI)-graphene oxide(GO)nicotine-imprinted composites with anti-swelling properties were prepared through cross-linking CS and PANI with GO.The swelling rate of the CS/PANI-GO nicotine-imprinted composite was 2.7%after soaking in water for 10 h.Nicotine as an adsorbent exhibited an adsorption capacity of 198 mg/g.Meanwhile,the selective adsorption capacity of the adsorbent was studied,and nornicotinine and cotinine were found to obtain adsorption selectivities of 2.97 and 2.4,respectively,indicating good nicotine specific adsorption performance.
