线性滴定是根据滴定点数据用回归手段求算被测物含量乃至平衡常数的滴定分析法。优点是操作简便,滴定范围宽。近年来由于化学计量学的发展和计算机的普及,应用日趋广泛。迄今以酸碱线性滴定程序的报道居多,但使用尚欠便利。本文基于酸碱滴定曲线方程建立回归模型,用Marquardt算法结合初值浮点数设定法和分布曲线布点法编制线性滴定通用程序。它提供三种求解方式的选择,可在PC-
Linear titration is based on the titration point data by regression to calculate the analyte content and even the equilibrium constant titration analysis. The advantage is easy to operate, titration range. In recent years due to the development of chemometrics and the popularization of computer, the application is more and more widely. So far, the majority of acid-base linear titration procedures reported, but the use still not convenient. In this paper, a regression model was established based on the acid-base titration curve equation. The general linear titration procedure was programmed by Marquardt algorithm combined with the initial value floating point setting method and the distribution curve distribution method. It offers three ways to choose the solution available in the PC-
