前言容量分析法是一种准确、可靠,应用广泛的定量分析方法,因而在化学分析发展过程中它一直占着重要的地位。即使在化学分析趋向于仪器化、自动化、计算化的今天,它仍然是化学分析中一种不可缺少的手段。容量分析的关键在于滴定终点的确定,一般确定终点的方法有指示剂法和电位法两种。指示剂法要求样品无色,并要有合适的指示剂;电位法适宜的范围虽广,但操作较繁,花费时间长。本文从寻找一种简便、快速、适宜范围广、容易实现自动化的滴定方法出发,将数学方法、电子计算机技术与容量分析结合,提出了一种新的滴
Foreword Volumetric analysis is an accurate, reliable, and widely used method of quantitative analysis that has always held an important place in the development of chemical analysis. Even though chemical analysis tends to be instrumental, automated and computational today, it is still an indispensable means of chemical analysis. The key to capacity analysis lies in the determination of the titration end point. There are two methods for determining the end point: indicator method and potentiometry. Indicator method requires colorless samples, and have the appropriate indicator; Potential range is suitable for a wide range, but the operation is complicated, take a long time. Starting from the search for a simple, rapid, suitable and wide range of titration methods that are easy to automate, this paper presents a new drop combining mathematical methods, computer technology and capacity analysis
