There has been a cumulative interest across the globe in substituting the synthetic materials with sustainable, economical, and biobased green alternatives for utilization in diverse industrial applications. Galactomannans are among the most important sustainable, biodegradable macromolecules abundantly produced by plants, which can be exploited for a range of end-use applications. Functionalization of the galactomannans may improve the physicochemical properties for diverse industrial applications. In the present study, the cationic derivative of Cassia tora gum, a 1:5 galactomannan, was synthesized under heterogeneous alkaline conditions using CHPTAC. The effect of each reaction parameter on the degree of substitution (DS) was investigated using Taguchi L16 orthogonal array. The optimized cationic product with DS 0.28 showed promising results as a biopolymeric flocculant for wastewater treatment and as a wet strength additive for improving the physical strength of paper prepared from old corrugated carton for its recycling. The optimized product was characterized by advanced spectroscopic methods.

野生物种阳离子半乳甘露聚糖作为湿强度添加剂和絮凝剂的应用、合成和表征



全球各地对用可持续、经济和生物基绿色替代品替代合成材料以用于各种工业应用的兴趣日益浓厚。半乳甘露聚糖是植物大量产生的最重要的可持续、可生物降解的大分子之一,可用于一系列最终用途。半乳甘露聚糖的功能化可以改善多种工业应用的理化性质。在本研究中,使用 CHPTAC 在异质碱性条件下合成了决明胶的阳离子衍生物(一种 1:5 半乳甘露聚糖)。使用田口 L 16正交阵列研究了每个反应参数对取代度 (DS) 的影响。 DS 0.28 的优化阳离子产品作为废水处理的生物聚合物絮凝剂以及作为湿强度添加剂来提高由旧瓦楞纸箱制备的纸张的物理强度以进行回收,显示出良好的结果。优化后的产品通过先进的光谱方法进行了表征。
