What is it about?
This review paper summarizes the current research on the preconcentration of pharmaceticals by graphene-based nanomaterials and provides valuable information about their applications in the determination and analysis of pharmaceuticals in various samples of health and environmental importance. Finally, the different analytical techniques used for the preconcentration of pharmaceuticals as well as their adsorption mechanism, and different environmental factors affecting the adsorption, have been studied and discussed in details.

Why is it important?
The presence of pharmaceuticals in the environment can be fatal and is a potential threat to humans, plants, and animals. Most of them are not readily biodegradable, and their long-term presence in water bodies may produce drug-resistant bacteria, which necessitates the elimination of pharmaceuticals from wastewater. For this purpose graphene-based nanomaterials (GBNMs) have been extensively applied as the efficient Solid Phase Extraction (SPE) adsorbents for the extraction of pharmaceuticals. Magnetic solid-phase extraction (MSPE) is found to reduce the time and cost of the operation by skipping the centrifugation step.
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long-standing collaborations. This article also describes the bad impact of pharmaceuticals on the humans, aquatic plants, birds and fish.
