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.
考察了 6 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，以期筛选出一种优于 XAD-2 树脂的树脂，用于从蜂蜜中纯化黄酮类化合物。吸附容量为 XAD-2>AB-8>DM-130>D3520>NKA-9>聚酰胺，XAD-2、AB-8 和 DM-130 的解吸率无显著差异，高于 D3520、NKA-9 和聚酰胺。通过结合动力学解吸分析，对拟一级、拟二级和颗粒扩散动力学模型进行动力学吸附分析，AB-8 的吸附和解吸行为与 XAD-2 相似，优于其他四种树脂。通过 Langmuir 和 Freundlich 等温吸附模型分析，XAD-2 和 AB-8 吸附黄酮类化合物的最佳温度为 25°C。AB-8 树脂是从蜂蜜中纯化黄酮类化合物的一种高效、经济的选择。
