Abstract : Sorption of frequently occurring emerging pharmaceutical compound such as acetylsalicylic acid (ASA) with
single and composite graphene oxide based adsorbent was investigated in detail by conducting batch kinetic, equilibrium and
desorption experiments. Among all adsorbents studied, newly synthesized composite adsorbent resulted in good removal
efficiency (97.8%). The kinetic study show the equilibrium was reached within 8 hours and pseudo second order kinetic
model well fitted with experimental data and indicates physisorption plays a major role. On the other hand, Langmuir
isotherm was showed better fit compared to Freundlich isotherm which indicated that adsorption took place on homogenous
active layers of the adsorbent. Maximum adsorption capacities were estimated to be 15.4 mg/g for ASA. Desorption of ASA
were significantly higher (79.8%) in an organic solvent. This graphene based composite adsorbent was found to be a
suitable adsorbent for removing pharmaceuticals from domestic wastewater
