摘要/Abstract

摘要：以2-氨基口白啶与SO₂^-4缔合物为电活性物质，以邻苯二甲酸二丁酯(DBP)为增塑剂，制作PVC膜硫酸根离子选择性电极.实验结果表明，电极对硫酸根离子具有良好的选择性和较高的灵敏度，其线性响应范围为5.0×10^-7～1.0×10^-1mol·L^-1.用该电极测定水中的硫酸根离子含量，结果令人满意.

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
