Abstract: A PVC membrance SO2-4ion-electrode made up of a electroactive substance and plasticiser,was reported in this paper.The electroative substance was composed of 2-Aminperimidine and SO2-4.The plasticiser was made up of DBP.The experiment made clear that the ion-electrode had good selectivity and high sensitivity about SO2-4.The electrode gave a linear response range from 5.0×10-7 mol·L-1 to 1.0×10-1mol·L-1.This electrode has been used for determining SO2-4 in water.The result was satifactory.

Key words: Sulfate, ion-electrode, 2-Aminperimidine
