GREEN CHROMATOGRAPHY: THE ECO-FRIENDLY AND SAFER CONCEPT OF GREEN ANALYTICAL CHEMISTRYAbstract
Green analytical chemistry is an attempt to reduce the environmental hazards caused by chemicals and chemical processes. To avoid the use or formation of dangerous materials, the best way is to prevent pollution rather than cleaning up the process. Therefore, it is important to choose a method with the least harmful effects on the environment. The main focus or aim of green chromatography is to make a method greener at each and every step of analysis from sample collection to its determination. The present review includes the goals to achieve green chromatography using environmentally benign solvents and reagents, most recent contribution in the development of greener sample preparation since it has effect on whole analytical methodology, chromatographic separation techniques, advantages of green chromatography, green microextraction techniques (solid-phase microextraction, still bar sorptive, liquid-phase microextraction) are included. The aim is to make chromatographic separations greener, depending on the type of chromatography which includes the solventless extraction technique.
