Green sorbents for the solid phase extraction of trace species

Abstract

Evaluating environmental sustainability is essential for determining the possible benefits of utilizing eco-friendly actions. There is increasing interest in analytical chemistry in developing and using environmentally friendly extraction processes. This review explores the advent and importance of green adsorbents as extractive materials in analytical chemistry applications. Sustainable green adsorbents from renewable sources provide an environmentally friendly alternative to conventional extraction techniques, reducing adverse environmental impacts and supporting a circular economy. This review focuses on various green adsorbents, including natural adsorbents, synthetic adsorbents like molecular imprinted polymers, metal–organic frameworks, covalent organic framework, nanomaterials, and carbon-based materials and their applications. Furthermore, green adsorbents are integrated with the principles of green analytical chemistry (GAC), which prioritizes reducing or eliminating harmful reagents and solvents. As the scientific community continues to prioritize sustainable practices, adopting green sorbents in analytical chemistry holds promise for advancing both environmental stewardship and analytical methodologies.
