摘 要：
在外加磁场磁感应强度为1.0T时,对原液质量浓度为4.88mg/ml的葛根黄酮溶液,在pH值为7的中性环境下,分别研究磁性树脂的静态和动态吸附,并就使用次数与普通树脂进行比较。结果显示:静态吸附时磁性树脂与普通树脂的吸附效能相差不大;当吸附流速为2BV/h时,磁性树脂达到饱和吸附时可处理12BV量的黄酮溶液,优于普通树脂;在使用4次后,磁性吸附树脂的吸附效果明显优于AB-8树脂。

摘 要：
Magnetic absorption resins displays more unique characteristics than ordinary adsorption resins due to its magnetism. The absorption efficiencies of magnetic resin in external magnetic field were investigated. The static and dynamic adsorption and reuse cycles of magnetic resin and AB-8 resin were compared with the intensity of the magnetic field at 1.0 T and pH=7, The results showed no significant difference between magnetic resin and AB-8 resin during static absorption, while in dynamic absorption when the flow rate of adsorption was 2 BV/h, magnetic resin was able to adsorb 12 BV flavonoids solution. After reusing 4 times, the adsorption of magnetic adsorption resin was better than AB-8 resin.
