一、分析化学方法发展概述分析化学是人们获得物质化学组成和结构信息的科学。进入 2 0世纪 ,随着科学技术的发展 ,相邻学科之间的相互渗透 ,使分析化学的发展经历了三次变革。第一次是在本世纪初 ,由于物理化学理论的发展 ,为分析化学提供了理论基础 ,建立了溶液中四大平衡理 I. Overview of Development of Analytical Chemistry Methods Analytical chemistry is the science by which people obtain material and chemical composition and structure information. Into the 20th century, with the development of science and technology, the mutual penetration of adjacent disciplines, the development of analytical chemistry has undergone three changes. The first is at the beginning of this century, due to the development of physical chemistry theory, to provide a theoretical basis for the analysis of chemistry, established four equilibrium solution
