摘要：

本文比较了北京大学《定量化学分析简明教程》与国外主要分析化学教材中定量化学分析的一部分内容，主要涉及误差与分析数据处理、溶液中的化学平衡与容量滴定分析。各教材对化学分析部分的基本内容、方法与思路基本一致，对内容展示的方式、顺序、切入点有所不同，为读者提供了不同的视角。《定量化学分析简明教程》在保证阐明基本概念、原理与方法的前提下，保持简明特色。国外大部分教材对溶液中的化学平衡基本概念进行详细介绍，适合没有学过普化原理的学生学习。未来的分析化学教材中，化学分析的内容可能会因为学科前沿的发展、新方法的出现而精简，建议适当加强在建立分析方法中涉及的步骤或流程、误差与数据处理的内容，建议涵盖建立分析化学方法应考虑的问题(即分析化学语言)以及分析方法特性评价的部分，建议进一步凝练溶液中化学平衡问题处理的思想方法，因为这些构成了理解分析化学思路的基础，以及发展分析方法和实施认证新方法的保证。

Abstract:

This paper gives a brief comparison of the quantitative chemical analysis content in representative analytical chemistry textbooks by authors at Peking University and overseas. Specifically, the content of introduction, error and data analysis and treatment, as well as chemical equilibria and volumetric titration are evaluated. The compared textbooks cover largely the same basic contents, methods and ways to solve analytical problems. Each book presents the content in its own style, sequence, and point cut, providing diversified perspectives on analytical chemistry. Quantitative Chemical Analysis by authors at Peking University is a concise textbook which elucidates all the basic concepts, principles and methods in limited number of pages. Most overseas textbooks provide a detailed introduction of the basic physical chemistry perspective of chemical equilibria, thus, general chemistry course may not be a prerequisite. The future development of analytical chemistry and related disciplines, as well as the emergence of new analytical methods may become parts of the analytical chemistry textbooks. As a result, the chemical analysis part may be reduced as we cannot make the size of the textbook bigger and bigger without limit. Nevertheless, the procedure and steps to solve problems of analytical chemistry remains the same. In the future analytical chemistry textbooks, the basics and principles in the workflow of the analytical chemistry procedure, and errors and analytical data treatment are suggested to be enhanced. The language/terminology of analytical chemistry and figures of merit of analytical methods are suggested to be introduced. The way to solve complicated chemical equilibria should be further condensed based on the physical chemistry principle. All of the above are the basis for understanding how to solve an analytical chemistry problem, how to develop an analytical method, and how to validate a new analytical method.
