The adsorption and desorption characteristics of six different resins (NKA-9, XAD-2, AB-8, D3520, DM-130 and Polyamide) were investigated, in order to screen one resin compared favorably with XAD-2 resin for the purification of flavonoids from honey. The adsorption capacity was XAD-2 > AB-8 > DM-130 > D3520 > NKA-9 > Polyamide, and the desorption ratios of XAD-2, AB-8 and DM-130 had no significant differences, which was higher than those of D3520, NKA-9 and Polyamide. By analyzing kinetic adsorption using pseudo-first-order, pseudo-second-order and particle diffusion kinetics models combined with kinetic desorption, the adsorption and desorption behavior of AB-8 was similar to that of XAD-2, which was excellent than other four resins. The optimal temperature for XAD-2 and AB-8 to adsorb flavonoids was 25 °C under the analysis of Langmuir and Freundlich isotherms models. AB-8 resin offers an efficient and economical choice for the purification of flavonoids from honey.

六种树脂对蜂蜜中黄酮类化合物吸附和解吸特性的比较研究

研究了六种不同树脂(NKA-9,XAD-2,AB-8,D3520,DM-130和聚酰胺)的吸附和解吸特性,以便筛选一种与XAD-2树脂相比有利的树脂进行纯化。蜂蜜中的类黄酮。吸附容量为XAD-2> AB-8> DM-130> D3520> NKA-9>聚酰胺,XAD-2,AB-8和DM-130的解吸率无显着差异,高于D3520,NKA-9和聚酰胺的合成。通过使用伪一级,伪二级和粒子扩散动力学模型与动力学解吸相结合的动力学吸附分析,AB-8的吸附和解吸行为与XAD-2相似,比其他四个都好。树脂。在Langmuir和Freundlich等温线模型的分析下,XAD-2和AB-8吸附类黄酮的最佳温度为25°C。AB-8树脂为从蜂蜜中纯化黄酮类化合物提供了一种有效而经济的选择。
