摘要：Antibiotics are emerging contaminants which affect human health, livestock, aquatic life and also resistbiological wastewater treatment. Therefore, it is imperative to remove them from wastewaters. The presentinvestigation is aimed at removal of sulfamethaoxazole (SMX) using adsorption and advanced oxidationprocesses (AOPs) and to determine efficacy of various adsorbents and study their adsorption kinetics. Theaqueous solution of sulfamethoxazole (SMX) was treated using GAC, PAC and activated alumina. Advancedoxidation processes (AOPs) were conducted using photolysis (UV treatment) and photolysis with H 2 O 2 (UV+ H 2 O 2 treatment). Adsorption of SMX on GAC and PAC was found to be rapid. Adsorption of SMX on GACand PAC followed pseudo first order kinetics. PAC was found to be more effective. Removal of SMX after120 min at a dose of 5 g/L using PAC, GAC and activated alumina was 73.4%, 34% and 15.5%, respectively.In case of PAC, only intraparticle diffusion was operating, whereas for GAC both intraparticle diffusion andsurface adsorption were operating concurrently. Removal of SMX using UV treatment and UV treatment inpresence of H 2 O 2 was found to be 7.65% after 80 min and 7.67% after 110 min, respectively. Activatedcarbon was found to have superior behaviour as compared to activated alumina for the adsorption of SMX.Adsorption has been found more effective as compared to UV treatment and UV treatment with H 2 O 2 .
