Abstract
Due to scientific and public concern about the environment pollution,
environmentally friendly practices have been introduced in different areas
of society and research. Green analytical chemistry (GAC) is a rapidly
growing and established field. It is based on principles overlap with the
sustained development ultimate goals. It concerns mainly with the
development of environmentally friendly analytical procedures and
sample preparation techniques that minimize consumption of hazardous
reagents and solvents, and maximize safety for scientists and the
environment. This ambitious and quite new approaches not only occurring
in academia but also in industrial and pharmaceutical environment. The
majority of USP methods and methods that have been approved by the
food and drug administration (FDA) use organic solvents, corrosive and
toxic chemicals such as acetonitrile, tetrahydrofuran, benzene, chlorinated
reagents, etc. that are hazardous pollutants and/or carcinogenic, with no
other options currently available.
The aim of this work is to develop and validate greener analytical methods,
compared with the reported or official methods without compromising
efficacy through different strategies such as modifying already existing
method or replacing them with new techniques, making it possible to cut
or dramatically reduce the amounts of reagents and solvent consumed,
switching to more benign solvent and waste generated.
