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.
