| Abstract: | A new immobilized metal affinity(IMA) adsorbent was prepared by β-cyclodextrin(β-CD) bonded silica gel with iminodiacetic acid(IDA) as ligand.The prepared adsorbent was characterized by solid state ~(13)C CP/MAS NMR and elemental analysis.The IDA and CD contents in the adsorbent were determined to be 158 μmol/g and 136 μmol/g,respectively.The adsorption capability of the adsorbent to α-amylase was also studied. |
