Importance Of Green Analytical Chemistry

“Ultrasound-assisted pretreatment of solid samples in the context of green analytical chemistry”

Sample preparation has witness transforms in recent years, with the main efforts focused on acceleration, simplification, miniaturization and automation of the operations involved. Ultrasound is a clean, efficient energy that has dramatically improved many sample-preparation protocols. The unique conditions provided by acoustic cavitation have enhanced solid-sample pretreatments ( digestion, dissolution and extraction), which are typically applied prior to detection.
At present, awareness of green aspects has led many analytical chemists to consider key indicators (e.g., operation time, safety, volume/concentration of solvents and energy consumption)

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

Green Chemistry concepts, apply to an incredible diversity of scientific endeavor, which has invariable led to differences between and amongst both academic and industry regarding what constitutes Green Chemistry. Talking primarily of the pharmaceutical industry and considering the advances achieved toward promoting Green Chemistry globally,it is shocking how diverse the answers can be when acheived, engineers, biologists, and chemists are asked the simple question “What is Green Chemistry?” may be this should be expect considering that individual priorities change based upon a specific endeavor, altering the focus of Green Chemistry and as aresult the message, making general definitions difficult. A common impression obtained appears to be that many do not accurately know or fully understand the true motivations, drivers, and deciding factors that serve to inspire and define Green Chemistry, and in particular Pharmaceutical Green Chemistry. This commentary seeks to shed light upon key aspects with regard to the philosophy of Pharmaceutical Green
