Efficient nanocomposites, GO-Psf and RGO-Psf has been synthesised from polysulfone and graphene oxide. The synthesised nanomaterials were characterised using contact angle measurements, SEM, TEM, XRD, TGA, DSC, Raman and FT-IR analytical techniques. The reported polymeric nanomaterials are attractive due to their high surface area and thermal stability. The maximum adsorption capacity for ciprofloxacin is 82.781 mg/g and 21.486 mg/g on GO-Psf and RGO-Psf, respectively. The kinetic and adsorption analysis identifies the nanomaterials as attractive adsorbents for removal of antibiotic pollutant, ciprofloxacin from aqueous solution. [ABSTRACT FROM AUTHOR]
