GRAPHENE FROM SUGARCANE EXTRACT AND ITS APPLICATION ON ORGANIC DYES ADSORPTIONB.S. NAVEEN PRASAD, K. GOVINDARAJU, V. GANESH KUMAR, K.S. UMA SUGANYA AND K. VIJAI ANANDAbstract The present work deals in preparation of graphene from sugarcane extract via a facile green approach. Graphene silica composite (GSC) is prepared using silica gel and the formation of GSC was confirmed from Scanning electron microscopy (SEM) and Raman spectral analysis. Efficiency of graphene silica composite (GSC) in the adsorption of organic dyes from water was investigated using Congo Red (CR), Methyl Red (MR) and Eriochrome Black T (EBT) as model dyes. GSC was used as a suitable adsorbent for the removal of dyes (CR, MR and EBT) from aqueous solutions. The adsorption of dyes by GSC was observed by UV-vis spectroscopic analysis. UV results also showed higher adsorption efficiency of GSC with better adsorption of dyes from aqueous solution. The adsorption characteristics varied with the initial concentration of dyes in solution.
