Raw and modified clays and clay minerals for the removal of pharmaceutical products from aqueous solutions: State of the art and future perspectives

Abstract: The occurrence of pharmaceutical products (PPs) within environmental compartments challenges the scientific community and water treatment operators to find suitable and practicable removal solutions. Clay minerals are among the oldest and cheapest adsorbents used for the removal of organic and inorganic pollutants. However, despite their significant adsorption properties, little is known about their potential to remove organic contaminants such as pharmaceutical products from wastewater effluents. Hence, based… Show more

“…Under basic conditions (pH > 10), weak adsorption of sulfates is due to competition with highly concentrated hydroxyl ions (Dong et al, 2011). The relation between the uptake of ionic compounds and the protonation state of mineral surfaces was extensively characterized in clay sciences (Lambert, 2018; Thiebault, 2019). It appeared that anion adsorption is enhanced when background acidity was below the sorbent’s pH ZNPC (Mahamat Ahmat et al, 2019).…”

“…Efficient adsorbents from biological, organic or mineral origin have been developed for water treatment. The most important used adsorbents are polymeric resins [ 12 ], biomass [ 13 ], agricultural wastes [ 14 ], industrial by-products, silica beads [ 15 ], clay minerals, modified clays [ 16 ], zeolites [ 17 ], and activated carbon [ 18 ]. Among the cited materials, polymeric resins have the ability to adsorb a wide variety of organic, high surface area, wide pore structure range, and can be regenerated with no loss in their adsorption capacities.…”

“…The struggle against the development of AMR has conventionally been viewed as a medical problem (Bengtsson-Palme et al, 2018). However, the environment is now being acknowledged as a substantial contributor to the global spread of antibiotic resistance (Wellington et al, 2013& Singer et al, 20162019). Rivers and waterways are prominent examples of environmental settings that have been been identified as a major repository and route for dissemination of both low levels of antibiotics and antibiotic resistance genes (Pärnänen et al, 2019;Amos et al, 2015).…”
