Abstract
AbstractThe primary goals of green analytical chemistry (GAC) involve the development of novel analytical technologies or the modification of existing methods to incorporate procedures with reduced reliance on hazardous chemicals. Several approaches can be employed to achieve these objectives, including the utilization of environmentally friendly solvents and reagents, shortening chromatographic separation times, and the miniaturization of analytical devices. The review summarizes the evolution of GAC with its specific principles and with special emphasis on recent applications in modern era. A detailed exploration of the choice of green solvents and their practical utilization in green liquid chromatography (LC) techniques for environmentally friendly analysis of pharmaceuticals has been discussed. An ordinary description with a tabular illustration of various modern green analytical techniques like micellar LC, superheated water chromatography, high‐speed LC, enhanced fluidity LC, two‐dimensional LC, and aspects of gas chromatography has been thoroughly provided for concepts with their mechanism and limitations. GAC provides potential applications for food analysis, environmental analysis of pharmaceutically active compounds in the aquatic environment with special emphasis on strategies for greening LC and impurity profiling, and so on. Numerous benefits, limitations, and challenges that are linked to the field of GAC are highlighted in this review. We pay special attention to new green approaches, such as automation, miniaturization, direct analysis techniques, and some initiatives like the National Environmental Methods Index Label for Analytical Eco‐Scale assessment. In spite of many promising advancements, the understanding is still limited and challenging.
