Preparation of Metal Ions Adsorbent with High Adsorption Capacity by Coupling Glycine to Sepharose 4B

Abstract:

After Sepharose 4B polymer beads were activated by using epichlorohydrin, glycine was binded with them to prepare an immobilized carboxyl group ion exchange adsorbent. The coupling rate was that 18.3 mg Gly could be fixed by 1 g of wet Sepharose 4B beads. At pH 9, this adsorbent showed power adsorption to metal ions with Ca2+16.49 mg，Mg2+6.92 mg，Fe2+11.06 mg，Fe3+4.98 mg and Mn2+11.84 mg were respectively adsorbed by 20 g of wet Sepharose 4B beads during saturated adsorption. Moreover, this absorbent possessed the properties with good stability, regeneration easily and low cost.
