Three new hybrid organic/inorganic polymeric ligand-exchange chiral stationary phases were developed by radical chain transfer reaction and surface grafting on silica gel,and successfully used for the enantioseparations of DL-amino acids and DL-hydroxyl acids.The resolutions were achieved by using water containing 2.0×10~(-4) mol/L of CuAc_2 as a mobile phase,column temperature of 40℃,flow rate of 1.0mL/min and detection at UV 254 nm.The elution order of D-isomer before L-isomer was observed for all DL-amino acids resolved except DL-Pro.

The resolutions were achieved by using water containing 2.0 × 10 -4 mol / L of CuAc_2 as a mobile phase, column temperature of 40 ℃, flow rate of 1.0 mL / min and detection at UV 254 nm.The elution order of D-isomer before L- isomer was observed for all DL-amino acids resolved except DL-Pro.
