A nonwoven fabric of Konjac glucomannan (KGM) for the adsorption of tannin was fabricated by using electrospinning and then followed by deacetylation with alkaline solution. To analyze the adsorption dynamics of tannin, the time course of the adsorption of tannin on the nonwoven KGM fabric was measured by immersing the fabric in tannin solution at different concentrations of tannin and amounts of the fabric. The initial and late stages of the adsorption behavior could be expressed, respectively, by using a diffusion-limited equation and a stoichiometric equation. A discussion on the dependence of the control parameters on the adsorption behavior is presented. The results represent the first step to provide an effective adsorption procedure for tannin in the use of modified KGM fabric.

单宁在脱乙酰电魔芋葡甘聚糖织物上的吸附动力学。

通过静电纺丝，然后用碱性溶液脱乙酰，制备了用于吸附单宁的魔芋葡甘露聚糖（KGM）无纺布。为了分析单宁的吸附动力学，通过将织物浸没在单宁浓度和织物量不同的单宁溶液中来测量单宁在非织造KGM织物上的吸附时间。可以通过使用扩散限制方程和化学计量方程分别表示吸附行为的初始阶段和后期阶段。讨论了控制参数对吸附行为的依赖性。结果代表了在使用改良的KGM织物中提供有效的单宁吸附程序的第一步。
