滴定终点评价方式的比较与选择

Comparison and Selection of End-point Evaluation

随着社会经济与文化的不断进步,科学技术水平的不断提高,在化学技术领域,跟随时代发展而衍生出的新的分析方法层出不穷。但是滴定终点评价方式依靠其简易的操作方法、广泛的使用范围以及高准确度的分析结果在化学领域依旧得到广泛的研究和应用,其应用范围涉及农、医、药、食品、科研等各个领域,并在各领域的进步与发展中起到毋庸置疑的推动作用。滴定终点的评价方式之所以拥有如此高的地位与普遍性,经久不衰并持久发展,与其内在的重要性密不可分。本文从对滴定终点评价方式的分析介绍入手,通过对实验案例的剖析,详细展现滴定终点评价方式的使用方式、方法及分析比较适合不同实验的研究方法的优缺点,并结合实验研究特性选取适合于相应实验的滴定终点评价方式,展现滴定终点评价方式的实际应用。

With the continuous progress of social economy and culture,the level of science and technology continues to improve,in the field of chemical technology,follow the development of the times and derived from the new analytical methods after another. But the titration end-point evaluation method relies on its simple method of operation, wide range of use and high accuracy of the analysis results in the chemical field is still widely studied and applied,its scope of application of agriculture,medicine,food,scientific research and other fields,and in all areas of progress and development play a role in promoting the undoubtedly. The end point of the titration method has been so high status and universality,enduring and lasting development,and its intrinsic importance inseparable. In this paper,the analysis of titration end^point evaluation methods is introduced. Through the analysis of the experimental cases,the methods of using the titration end-point evaluation methods and the advantages and disadvantages of the different methods are analyzed in detail,and the suitable experimental characteristics are selected. In the end of the corresponding titration of experimental evaluation methods to show the end of the titration evaluation of the practical application.
