近三十年来,由于生产实际的需要,以及物理化学等基础科学和现代技术的迅速发展,化学分析方法和技术也发生了巨大的改变。这表现在微量和超微量分析、仪器分析以及色谱分析技术的建立,也表现在有机试剂和同位素等的广泛应用上。从而使古典的容量分析和比色分析等也有了很大的改观。有人曾对1953—1955年三年中有关比色分析的大量文献进行了综述,可以看出,现代的比色方法不仅在仪器设备上有了巨大改
In the recent three decades, chemical analysis methods and technologies have also undergone tremendous changes due to the actual needs of production and the rapid development of basic and modern technologies such as physical chemistry. This is manifested in the development of trace and ultramicro, instrumental and chromatographic techniques as well as the widespread use of organic reagents and isotopes. So that the classical capacity analysis and colorimetric analysis has also been greatly improved. A large volume of literature on colorimetric analysis from 1953 to 1955 has been reviewed. It can be seen that modern colorimetric methods not only have great changes in equipment
