Analysis of Water Purification Efficiency of Graphene Sand Nanocomposite

Abstract

Graphene oxides are known for their affinity towards ionic components. Hence this property could be utilized to remove the impurities present in water molecules. Moreover, Graphene oxides are popular for their antimicrobial and disinfective properties. Graphene nanocomposite was prepared with reduced sugar and sand mixture at nitrogen atmospheres at 200o C and was characterized using XRD, SEM-EDAX, UV- Visible spectroscopy and Raman’s spectroscopic techniques. Two different water mixtures were used for the purification purpose- ie., sewage and soft drink concentrate (Coca Cola). Graphene Sand Composite (GSC) was loaded for purification at different weight percentage compositions such as 1%, 3% and 5%. Water mixtures were analyzed for their chemical and physical properties before and after treatment with graphene nanocomposite. The microbiological load before and after treatment with the composite was also analyzed. All the characterization shows the presence of graphene functionalities, carbon functionalities, and other elements present in the GSC. The physical, chemical and microbial examination of purified coca cola and sewage water matches the features of pure water with less impurities and absence of pathogen. The current study reveals the importance of water purification application using GSC and the measurement of water purification efficiency with conventional techniques.
