In this study, clay mineral-based catalysts (Co/Kaolin) were prepared to activate peroxymonosulfate (PMS) for atrazine (ATZ) elimination. Rapid ATZ degradation (99.45 ± 0.22 % in 5 min) was observed in the Co/Kaolin + PMS system. EPR and Quenching experiments showed that SO₄^•- and •OH played a dominant role in the degradation of ATZ by PMS. DFT calculations demonstrated that the adsorption capacity of Kaolin with PMS was enhanced by the introduction of Co. Natural polysaccharide macromolecules (pectin) were applied as carrier for Co/Kaolin to facilitate the recycling of catalyst and reduce the leaching of Co. The cyclic degradation (6 times) confirmed that the Co/Kaolin-pectin/Co was stable in activating PMS to degrade ATZ (97.46 ± 0.44 %). The fluid bed degradation experiments exhibited the potential for long-term degradation of ATZ (96.34 ± 0.54 % in 8 h).

A large number of different adsorbents have been examined in the literature for their ability to adsorb dissolved pharmaceuticals. Most studies were undertaken at pollutant concentrations several orders of magnitude above those typically found in wastewater and focused on maximum adsorbate loadings as a performance criterion. This review draws on literature data regarding the adsorption performance of various pharmaceuticals by the most important adsorbent classes, including carbons, clays, silica, zeolites, and polymers. It demonstrates that the adsorption capacity alone is insufficient to describe an adsorbent’s efficiency in achieving the decontamination levels targeted by the EU. Instead, for typical European WWTP effluents with pharmaceutical contaminants in the lower ng to µg per liter range, both the adsorption capacity and the adsorption affinity of the adsorbent must be considered in order to determine the required adsorbent amount.
