Design, Development and Characterization of Graphene Sand Nano-Composite for Water Filtration
Nano-Composite for Water Filtration
Water purification and filtration is a global issue and many researchers are engaged to resolve this problem by adopting the scientific approach, graphene sand composite was prepared through bio- synthesized technique. River sand was used in this context to remove the impurities already present in the sand 0.1M nitric acid treated the sand and the product was powder black in colour, referred as GSC, graphene sand composite. SEM, XRD and FTIR characterization was used to analyze the results. SEM images showed nano sized layers or sheets of graphene extending outwards.The XRD peak represents the multi lagered graphene structure which is formed by the treatment of the composite with acid and application of the high temperature during experiment UV-visible spectroscopy results successfully reveals the filtration difference between mud water and filtered water.
