dc.description.abstractNaproxen is one of the mostly used drugs worldwide and is most abundant in wastewater. This study aims to adsorb naproxen from wastewater using magnetically modified carbon-based adsorbents. These adsorbents have very large specific area for naproxen adsorption, and magnetite modification provides easy separation and regeneration. The co-precipitation method was used for magnetic modification. Adsorption process was carried out in batches. The effect of adsorption variables was investigated. Langmuir, Freundlich, and Dubinin-Radushkevich isotherms were applied to the equilibrium data. The maximum adsorption capacities of adsorbents from Langmuir isotherm were found as 20.75 mg/g for magnetic multi-wall carbon nanotubes and 87.79 mg/g for magnetic activated carbon. Pseudo-first-order kinetic model, pseudo-second-order kinetic model, intra-particle diffusion model, and Bangham model were used for determination of adsorption mechanisms. The rate-limiting step is electron exchange between the adsorbent and adsorbate. Both film diffusion and intra-particle diffusion occur while the adsorption process. Delta GA degrees, Delta SA degrees, and Delta HA degrees were calculated for the process.en_US
