Spectroscopy: The Best Way Toward Green Analytical Chemistry?

Abstract Environmental issues are increasingly of global concern. The trend of sustainable development requires chemistry to be “clean” or “green.” In the 1990s, therefore, the concept of “Green Chemistry” was proposed, together with the “Twelve Principles of Green Chemistry.” These twelve principles encompassed the premise of green chemistry but mainly focused on the aspects of synthetic chemistry. For green chemistry in the analytical laboratory, the concept of Green Analytical Chemistry was subsequently proposed, but it has not yet become a popular field of chemistry. Apparently, green analytical chemistry is a key part of green chemistry and an important trend in analytical chemistry in modern society. It is an emerging area of increasing importance both in green chemistry and in analytical chemistry. In this report, green analytical chemistry is systematically discussed and then defined with seven principles. Firstly, the aspects of green analytical chemistry are discussed in detail with regard to the whole analytical process; i.e., from sample collection, sample preparation, to sample analysis, and some other related issues such as process analysis. Secondly, some naturally green or possibly green analytical techniques are discussed. Presently, spectroscopic methods dominate the area of green analytical chemistry. The purpose of this report is to arouse more attention to green analytical chemistry to serve the sustainable development of the modern society.
