自动电位滴定中的一阶导数二阶导数滴定曲线的绘制
Drawings of First Derivative Curve and Second Derivative Curve in Automatic Potential Titration
摘要
Abstract
The curves of the first derivative titration and the second derivative are often used in potential titration in order to determine the end of titration.It needs a large number of calculations of data and is difficult to accurately determine the endpoint.The using of Excel in processing experimental data of automatic potential titration was discussed,according to the mathematical models of potential titration data processing.An electronic sheet of data process of the potential titration was built,according to the models of calculation.Formula was added in sheet.The detailed steps of the program and the methods of titration data-processing are discussed.The chart can be drawn automatically as well.The data processing method can be prepared by the user,according to the user＇s situation.This method can be spread in the use of other analysis data processing.关键词
