pH-ISFET在电位滴定中的应用

The Application of pH-ISFET in the Potentiometric Titration

本文介绍了以pH-ISFET为检测器的电位滴定系统,研究了强酸与强碱的滴定。用pH-ISFET作为检测器,与其它种类检测器的滴定规律相似,pH-ISFET电位滴定系统可将被检测液的浓度下限拓展到10^(-5)N数量级。该系统辨认等当点的能力强,而且具有设备简单、操作方便、重现性好、适用性强等特点。

This thesis gives the introduction of the potentiometric titration system which uses the pH-ISFET as a detector, and it also gives the research work of titration of powerful acid and powerful alkali. Using the pH-ISFET as a detector, this system has the similar titration law to that of the systems which, use other kinds of detector, and lowest H4 concentration of the liquid which can be detected by this system reaches 10-5N. This system has many advantages over others: the powerful capacity of identifying the equivalent point of the titration, simple equipment, convenient operation, good repeatability, wide application and etc.
