多元酸酯系-PVC膜碳传感器的研制及电位滴定中的应用

简要报道一种新型的多元酸酯系-碳PVC（CPE）传感器,它制作简单、实用,已证实适合于化学容量分析中几种类型的滴定,如“沉淀滴定”,“氧化还原滴定”,“酸碱滴定”,“非水溶剂滴定”和某些形成络合物反应的滴定中作指示电极使用。以电位指示终点所获结果与标准化学方法吻合。

Polybasic Ester-Carbon PVC Membrane Sensor and Its Application in Potentiometric Titration

In this paper, a new type of polybasic ester membrane sensor were studied. The carbon was modified by PVC on CPE solution and covered with a film of polybasic ester by manual. The sensor exhibits fast and long-term stability, experimental results show that sensor can be used in many field of analysis, such as acid-buse titration, "redox titration," "precipitation titration,"complex ion titration and in non-aqueous solvent titration. The end point of titration can be detected by potentiometer. The results obtained agree well with standard chemical analysis meth ods, accuracy also satisfactory, and rnay have wide prospect to application.
