摘要
EDTA—金属离子滴定是定量分析络合滴定中最基础的部分,很多络合滴定分析都与EDTA有关.但由于这类滴定分析中常同时伴随着酸效应、共存离子效应等副反应的发生,使得分析结果的计算较为复杂.本文根据EDTA滴定的基本原理,将有关参数存放在数据库中,利用VB设计编程,通过人机对话输入滴定分析测定数据和调用数据库即可进行计算,使EDTA滴定的结果处理变得非常简捷、方便.
It is essential for complexometric titration of EDTA-M^(n+) (ethy lenediamine tetraacetic acid & metal ion) in quantive analysis.The treatment of EDTA-M^(n+) is very complex because of side reactions such as acid effect and coexist ion effect companying with titration.Therefore,according to the radical principle of EDTA-M^(n+) we program with Visual Basic Program Language to deal with this problem. If we input analytical datas in man-machine conversation way,the program will transfer parameters in database which had been built before calculation. As a result,the treatment of EDTA-M^(n+) titration becames more convenient and succinct.
