In the sugar industry, eliminating side impurities throughout the manufacturing process is the most significant obstacle to clarifying sugar solutions. Herein, magnetic chitosan (MCS) nanocomposite was Fabricated to be used as a biodegradable, environmentally friendly clarifying agent throughout the cane juice and sugar refining processes. FeO was synthesized using the coprecipitation procedure, and then MCS was combined using a cross-linking agent. Furthermore, 14.76 emu g was the maximum saturation magnetization (Ms) value. Because MCS is magnetically saturated, it may be possible to employ an external magnetic field to separate the contaminant deposited on its surface. Additionally, zeta potential analysis showed outstanding findings for MCS with a maximum value of (+) 20.7 mV, with improvement in color removal % up to 44.8% using MCS with more than 24% in color removal % compared to the traditional clarification process. Moreover, utilizing MCS reduced turbidity from 167 to 1 IU. Overall, we determined that MCS nanocomposite exhibits considerable effectiveness in the clarifying process for different sugar solutions, performing as an eco-friendly bio-sorbent and flocculating material.
在制糖工业中,在整个制造过程中去除杂质是澄清糖溶液的最大障碍。在此,制备了磁性壳聚糖(MCS)纳米复合材料,用作甘蔗汁和糖精炼过程中可生物降解、环保的澄清剂。采用共沉淀法合成FeO,然后使用交联剂将MCS复合。此外,最大饱和磁化强度(Ms)值为14.76 emu g。由于MCS具有磁饱和性,有可能利用外部磁场分离沉积在其表面的污染物。此外,zeta电位分析显示MCS的结果优异,最大值为(+)20.7 mV,与传统澄清工艺相比,使用MCS时脱色率提高了44.8%,脱色率超过24%。此外,使用MCS可将浊度从167降低至1 IU。总体而言,我们确定MCS纳米复合材料在不同糖溶液的澄清过程中表现出相当高的有效性,可作为一种环保型生物吸附剂和絮凝材料。
