Abstract:

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.

Key words: molecularly imprinted composite, nicotine, adsorption, chitosan, graphene oxide
