Abstract :

Graphene sand composite was prepared as part of the final year project through biosynthesized process from the sugar anchoring on sand particles without any binder resulting in a composite, referred to as graphene sand composite (GSC), which is used in water filtration. River sand was firstly treated with 0.1 M nitric acid to remove impurities, washed with deionized water and dried at 100�±3�°C. 20 gm of sand was added in 1 M sugar solution, magnetically stirred for 5 hours at 85oC and then allowed to get dried. Then the mixture was placed in the crucible and covered with activated charcoal and heat treated in muffle furnace for 6 hours, with specified cycle, subsequently powder was treated with concentrated sulfuric acid and washed with deionized water. Later this powder was dried at 120oC on a hot plate, which resulted in a black powder, known as graphene sand composite. The morphology and composition of the synthesized Graphene Sand Composite (GSC) was investigated by means of X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infra-Red Spectroscopy (FTIR). SEM images show wrinkly edges and this is the characteristic of graphene morphology. Filter of GSC was made and different samples were analyzed by UV-Visible spectroscopy and different tests were taken to analyze drinkability of filtered water.
