Abstract/OtherAbstract:
Retaining the inherent hydrophilic character of GO (graphite-oxide) nanosheets, sp2 domains on GO are covalently modified with thiol groups by diazonium chemistry. The surface modified GO adsorbs six fold higher concentration of aqueous mercuric ions than the unmodified GO. 'Core-shell' adsorbent granules, readily useable in filtration columns, are synthesized by assembling aqueous GO over sand granules. The nanostructured GO coated sand retains at least five fold higher concentration of heavy metal and organic dye. The research results could open avenues for developing low-cost water purification materials for the developing economies.
