| Abstract: | A new kind of weak cation stationary phase was prepared with poly maleic acid encapsulated silica matrix. This weak cation silica column has superior separation ability for the alkaline metal, alkaline earth metal and monovalent amine cations. Moreover, the sepa- ration of monovalent and divalent cations can be well obtained in the same ion chro- matographic condition. The influences of pH and the concentration of eluent on the retention of metal cations have been studied. |
