摘    要:以壳聚糖为原料,在微波辐射下,根据模板法制备了具有Cu2+空穴的球形胺化交联壳聚糖树脂.采用FT-IR和SEM对树脂的形貌和结构进行了表征,并对影响树脂吸附性能的因素进行了研究.结果表明,树脂具有能够吸附金属离子的活性基团,表面颗粒均匀;当无水乙醇为3mL、环氧氯丙烷为5mL、四乙烯五胺为4.8 mL、胺化时间为3 min时,制得的壳聚糖树脂对Cu2+具有良好的吸附性能,吸附容量为326.55 mg/g.

关 键 词:微波辐射  Cu2+模板法  壳聚糖树脂  吸附

Abstract:With chitosan as raw material,a spherical amination crosslinked chitosan resin with Cu2+ vacancy was prepared using template method under microwave irradiation.The structure and morphology of the chitosan resin were characterized by Fourier transformation-infrared and scanning electron microscopy,respectively.The influencing factors on its adsorptivity were also investigated.The results show that the resin has active groups to adsorb metal ions and its surface particles are homogeneous.The adsorptivity of the chitosan resin for Cu2+ was up to 326.55 mg/g when the chitosan resin was prepared with the conditions of 3 mL of ethanol,5 mL of epichlorohydrin,4.8 mL of tetraethylenepentamine and 3 min of amination.
Keywords:microwave irradiation  Cu2+ template method  chitosan resin  adsorption
