以环氧氯丙烷和三乙胺为原料,合成了环氧丙基三乙基氯化铵,与壳聚糖进行共价交联后负载到沸石上,制得了N-季铵化壳聚糖/斜发沸石杂化材料。通过傅里叶变换红外光谱仪、扫描电子显微镜、纳米粒度仪和Zeta电位分析仪对季铵化壳聚糖的结构、杂化材料的微观形貌、粒径、Zeta电位等进行了表征,考察了杂化材料的吸附性能。结果表明:环氧丙基三乙基氯化铵与壳聚糖以共价键相结合;杂化材料为均匀稳定的分散体系,整体分散明朗清晰,粒径呈单峰分布,平均粒径为3216.7nm,Zeta电位为+38.46mV,对腐殖酸具有良好的吸附性能。
Epichlorohydrin and triethylamine as raw materials, the synthesis of epoxypropyl triethylammonium chloride, with chitosan after covalent cross-linked to the zeolite, prepared N-quaternized chitosan / Clinoptilolite hybrid material. The structure of quaternized chitosan, the micromorphology, particle size and Zeta potential of the hybrid materials were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, nanoparticle size analyzer and Zeta potential analyzer. The effects of Adsorption properties of hybrid materials. The results showed that: epoxypropyltriethylammonium chloride and chitosan covalently bonded; hybrid materials for the uniform and stable dispersion, the overall clear and clear dispersion, the particle size distribution was a single peak, the average particle size was 3216.7nm, Zeta potential of +38.46mV, humic acid has good adsorption properties.
