Abstract

In this short communication, we report a novel and inexpensive approach to synthesize Beta-Cyclodextrin functionalized Graphene Oxide (GOCD) which has been fabricated for the adsorption of water soluble organic dyes from aqueous solution. The adsorbent GOCD has been synthesized using facile sonochemical route and accordingly characterized using techniques such FTIR, TGA, RAMAN and TEM respectively. Brilliant green dye (BG), a cationic, water soluble dye, commonly used as green pigment in textile/dye printing technology, is a highly toxic compound and consequently GOCD has been employed for its removal before recyclability of the waste water. The adsorption study of BG onto GOCD is investigated using UV-vis absorption spectroscopy. The exploration established the fact that the as-synthesized material GOCD has appreciable capability in dye removal and therefore possesses significant roles in waste water treatment technology.
