Abstract:

In order to fulfill organic combination of professional goal and moral goal from the course of instrumental analysis and student education, and unification of green analytical chemistry from discipline concept and the social responsibility of green development, greenness the evaluation index for describing the greening of analytical methods was introduced into our instrumental analysis course. Firstly, the development of green chemistry, green analytical chemistry and green liquid chromatography was briefly covered. Secondly, various methods for quantitative expression of greenness were presented, and the two methods of HPLC-EAT and CHEMS-1 were emphasized, involving their usages, scope of application and limitations. Finally, the two methods were employed for calculating the greenness values of the liquid chromatography methods selected from literatures, and the correlation analysis between the calculation results from the two methods were done. It was shown that the data from the two methods were not the same, but their correlation was good. Both HPLC-EAT and CHEMS-1were capable of measuring greenness of liquid chromatography, and the two methods were easy for students to grasp. We would like to recommend that the concept of greenness and together with the two methods for calculating greenness should be adopted in instrumental analysis textbooks in the future.

Key words: Greenness, Green chemistry, Chromatography, Instrumental analysis course
