Judging the Greenness of Analytical Method using Ecological Foot Prints: A Green Metric Approach

Abstract

Green Analytical Chemistry advocates for the utilization of environmentally friendly chemicals and reagents, energy conservation in laboratory equipment, and the reduction of waste to a minimum. Recent developments in analysis involve the reduction in size of analytical instruments, the use of solventless or solvent-minimized extraction techniques, and the utilization of less hazardous solvents. The twelve principles of Green Analytical Chemistry (GAC) guide these advancements, which include sustainable practices into analytical procedures. Although these guidelines give direction, unavoidable processes may still hinder green analytical techniques. Thus, analytical procedures must be assessed for their impacts on the environment and occupation and minimised if feasible. To measure the greenness of analytical methodologies, many criteria have been devised. The Analytical Eco-Scale, Analytical Greenness (AGREE) Metric, and Green Analytical Procedure Index (GAPI) calculate green indexes for analytical procedures by considering several components of the process. This overview explains the fundamentals of the tools or metrics and discusses their use in analytical methods. It also highlights user positives and downsides of various measures. Comparing evaluation findings based on solvents and reagents availability helps researchers identify the most eco-friendly strategy. This work intends to inspire new green analytical chemistry views and advances by illuminating these assessment techniques and their consequences.
