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