PURIFICATION OF CONTAMINATED WASTEWATER WITH THE HELP OF GRAPHENE COMPOSITES WITH HYDROGELS

Abstract

Lack of clean water requires the use of new wastewater treatment technologies. Adsorption is a simple and effective method for removing contaminants from contaminated water. Graphene composites with hydrogels have found application in wastewater treatment because they have unique properties such as porous structure, unique morphology, good rheological properties, non-toxicity, etc. The paper presents a literature overview of potential solutions to wastewater treatment using composite graphene and graphene oxide with hydrogel-like adsorbents. The mentioned composite compounds have been used in the treatment or elimination of various hazardous substances. In this work, we have investigated the possible adsorption of different classes of colored pollutants (paints) and pesticides (both organic and inorganic).
