摘    要:利用微波辐射法合成了甲醛交联壳聚糖香草醛希夫碱,用IR和XRD对其结构进行了表征,并用UV吸收光谱比较了甲醛交联前后壳聚糖香草醛希夫碱在酸中的溶解性能.吸附实验表明,该壳聚糖改性产物对一些金属离子的吸附性能与壳聚糖香草醛希夫碱和甲醛交联的壳聚糖有所不同,对Cu2 具有良好的吸附选择性,并且在酸性环境中几乎不溶解,因此可用作Cu2 的选择性吸附剂.

关 键 词:壳聚糖  改性  微波辐射  吸附

Abstract:A cross-linked chitosan vanillin Schiff base was synthesized by formaldehyde under microwave radiation,whose structure was then characterized by means of IR and XRD.The solubility of the product in acidic solutions was also compared with that of chitosan vanillin Schiff base using UV absorption spectrum.The adsorption experiment showed that,as compared with chitosan vanillin schiff base and cross-linked chitosan by formaldehyde,the product is of different adsorption capability for some metal ions.Moreover,as the product possesses excellent selective adsorption for Cu~(2 ) and is insoluble in acid conditions,it can be used as a selective adsorbent of Cu~(2 ).
Keywords:chitosan  modification  microwave radiation  adsorption
