| 摘 要： | 关于线性滴定的理论、方法及特点已有专门文献介绍[1-4],县体分为图解法和计算法两类.前者直观性强,对所用仪器的精度要求不高,但依靠手工作图,不仅费时费力,而且不免引入主观误差;后者计算繁杂,必须使用高功能电子计算机,本文在图解法基础上引入微机绘图,并自动剔除可疑值,再由微机进行回归处理,直接打印结果.

| Abstract: | In the linear titrations, two methods arc commonly used, the graphic method and the calculating method. The present paper describes a new method on the basis of the graphic method, namely, graphic regressive method. According to this mcthod, the graphs are drawn by microcomputer, and the results are obtained by the use of linear regression equations. Thus, the present method saves both time and labour compared with the former two methods. By appling this method to determine several very weak acids and weak acid mixture,we obtained satisfactory results in all cases. |
