Sažetak
Organic micropollutants (OMPs) present in wastewater have been brought into focus these last years. Despite their low concentrations in wastewater effluents (ng/L - µg/L) (Verlicchi et al., 2012), they entail potential risks for human health and the environment due to their occurrence and persistence. Among the innovative treatment technologies used, adsorption onto powdered activated carbon (PAC) seems a promising option for the removal of OMPs. However, previous studies have found that the dissolved organic matter (DOM) present in wastewater is the main factor limiting the adsorption of OMPs onto activated carbon (Guillossou et al., 2020 ; Zietzchmann et al., 2016). Yet it is not clear what effects DOM constituents have on OMPs adsorption. In this study, adsorption batch tests were performed in ultra-pure water and humic acid solution for the removal of diclofenac, sulfamethoxazole, and trimethoprim by testing two different PAC concentrations (0.1g/L and 1g/L). Kinetic experimental data obtained were fitted to Lagergren's pseudo-first order, pseudo-second order, and intraparticle diffusion model. In order to describe the mechanism of adsorption, the data obtained were fitted to linear (Kd), Freundlich, and Langmuir isotherms. Matrix effect caused by the presence of humic acids is expected to decrease the adsorption of OMPs according to the DOM present in the solutions.
