Abstract

Porous chitosan/saccharomycetes adsorption microspheres were successfully prepared by using silica gel as porogen. The morphology of porous chitosan/saccharomycetes microspheres was characterized by scanning electron microscopy, the interaction between molecules was characterized by Fourier transform infrared spectroscopy, and the crystallization property of the microspheres was characterized by X-ray diffraction. The results showed that the adsorption sites of amino and hydroxyl groups had been provided by the porous chitosan/saccharomycetes microspheres for the removal of preservatives, pigments, and other additives in food. The surface roughness of microspheres could be improved by increasing the mass ratio of saccharomycetes. The increase in silica gels could make the microsphere structure more compact. The porous chitosan/saccharomycetes microspheres could be used as adsorbents to adsorb doxycycline in wastewater.

摘要

以硅胶为致孔剂成功制备了多孔壳聚糖/酵母菌吸附微球。采用扫描电子显微镜对多孔壳聚糖/酵母菌微球的形貌进行表征，利用傅里叶变换红外光谱对分子间相互作用进行表征，通过X射线衍射对微球的结晶性能进行表征。结果表明，多孔壳聚糖/酵母菌微球提供了氨基和羟基等吸附位点，可用于去除食品中的防腐剂、色素及其他添加剂。增加酵母菌的质量比可提高微球的表面粗糙度。增加硅胶用量可使微球结构更致密。多孔壳聚糖/酵母菌微球可作为吸附剂用于吸附废水中的强力霉素。
