摘要:

采用壳聚糖(CS)和聚苯胺(PANI)与氧化石墨烯(GO)交联构建了抗溶胀性的CS/PANI⁃GO尼古丁分子印迹复合材料。结果表明,其在水中浸泡10 h的溶胀率为2.7 %。该复合材料作为吸附剂对尼古丁的吸附容量达到了198 mg/g。研究了吸附剂的选择吸附能力,对降烟碱和可替宁的吸附选择性系数分别达到了2.9和2.4,表明其具有良好的尼古丁特异性吸附性能。

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
