Abstract:

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.
