WHAT IS GRAPHENE OXIDE AND HOW IS IT MADE?
Graphene oxide is a single layer of carbon atoms that are bonded together in a hexagonal pattern. The oxygen functional groups such as hydroxyl, epoxide, and carboxyl groups are attached to its surface through chemical oxidation, which results in the creation of a highly reactive material. Graphene oxide is produced using a process called exfoliation, which involves the breaking apart of graphite into individual layers of graphene.
This can be done using chemical, mechanical, or thermal methods. The chemical method involves the oxidation of graphite using a strong oxidizing agent, such as sulfuric acid or nitric acid.
ADVANTAGES OF GRAPHENE OXIDE FOR ENVIRONMENTAL REMEDIATION AND POLLUTION CONTROL
Graphene oxide has several advantages that make it a promising solution for environmental remediation and pollution control.
Large surface area: Graphene oxide has a high surface area-to-volume ratio, which makes it highly effective at adsorbing pollutants and toxic substances.
High conductivity: Graphene oxide is an excellent conductor of electricity and heat, making it useful in electrochemical processes for the removal of pollutants from water and air.
Chemical stability: Graphene oxide is highly resistant to chemical degradation, making it an ideal candidate for use in harsh environmental conditions.
Biocompatibility: Graphene oxide is non-toxic and biocompatible, making it safe for use in environmental remediation and pollution control processes that involve human exposure or contact with the environment.
Reusable: Graphene oxide can be easily recovered and reused after use, making it a cost-effective solution for long-term pollution control.
