摘要
The cation exchange capacity (CEC) of different cation and the total CEC have been determined by the ammonium chloride exchange-atom absorption spectrograph methods and the CaCl2-formaldehyde condensation method for three phlogopite-vermiculite interstratified mineral samples. Influences of the sample granularity and the pH value of the solution on the CEC have been studied. The result indicated that, along with granularity enlargement, the CEC of the samples reduced gradually. But along with pH value enlargement, the CEC of the samples reduced sharply initially (pH=2～5); then went gently (pH=5～9); finally reduced sharply again (pH=9～11.5).
