One of the most important problems nowadays is the contamination of the environment and more specifically of surface and underground waters by toxic substances, e.g., heavy metals and organic pollutants. Shortage of supplies of potable water is occurring in many areas worldwide, owing to the steady increase of the population, yielding to the harsh exploitation of water resources by human activities, which introduce many contaminants, including organic dyes, heavy metal ions, salts of light metals. In order to contrast what has by now already turned into one of the most severe concerns in the world’s community, it is necessary to carry out the decontamination of wastewater. Graphene oxide (GO) is a valid candidate for the absorption and removal of pollutants in water.

Graphene material is gradually being used in the fields of electronic technology and biomedicine due to its properties such as ductility, expandability and flexibility. The author gets efforts to explore some commercial graphene products such as graphene materials, aims to demonstrate a method to monitor the status of such a filter in real time during its operating phases: pollutant adsorption, saturation, and regeneration.

This study first showed that all types of graphene have excellent adsorption properties. This appears to be due to its large available surface area. This experiment provides a reference for exploring low-cost graphene materials and products preparation. With the continuous discovery of the properties of graphene and its composites and the continuous innovation of the preparation process, graphene will be applied to various devices in daily life and become an indispensable part of our lives.
