ZG106Ca~(2+)树脂分离果葡糖浆的吸附热力学与动力学研究
|
摘要
以ZG106Ca~(2+)树脂分离果葡糖浆的吸附性能为研究内容,分析ZG106Ca~(2+)树脂的吸附等温线、吸附热力学性质和动态吸附参数,结果表明,在静态吸附试验条件下,ZG106Ca~(2+)树脂对果葡糖浆中果糖的吸附是吸热过程,吸附能力较弱,吸附参数用Freundlich方程拟合较好,相关系数均大于0.95。动态吸附研究表明,ZG106Ca~(2+)树脂对果糖的吸附能力显著大于对葡萄糖的吸附能力,这种吸附能力差异的理论与模拟移动色谱能够高效分离果葡糖浆的实践相吻合。
In this paper, adsorption properties of ZG106Ca~(2+) resin separation of fructose glucose syrup were researched, and the adsorption isotherm, thermodynamic properties and dynamic parameters of ZG106Ca~(2+) resin were analyzed. The results indicated that under experimental conditions of static adsorption, the adsorption of ZG106Ca~(2+) resin for fructose in high fructose corn syrup was an endothermic process, and the adsorption capacity was weak, the adsorption parameters fit Freundlich equation well, and the correlation coefficient was greater than 0.95. The results of dynamic adsorption showed that the adsorption capacity of fructose for ZG106Ca~(2+) resin was significantly greater than that of glucose,which was consistent with the verification test of high efficient separation of fructose syrup by simulated moving bed.
