Amino modification of macroporous resin and its adsorptive properties to rutin

Using self-made chloromethyl polystyrene as raw material, the amine reaction was performed in certain conditions. As the result, several different polar aminated hypercrosslinked resins were synthesized and characterized by FT-IR and SEM. The results show that the adsorption and elution of several amino resins to rutin were different. The adsorption and elution ability of the resin modified by 1,6-diaminohexane (HMD) to rutin were strongest in three kinds of resins, and better than usual of market products macroporous resin AB-8 and D101 (crosslinked styrene-divinylbenzene copolymers). The isothermal adsorption curve of the resin could be simulated by Freundlich isotherm equation. This study about the adsorption and elution to rutin provides not only several new resins, but also a new method for the separation of natural product.
