“…Despite their low concentration, ECs cause adverse ecological effects on human and animal health (Zhou et al 2020 ). The main groups of ECs are pharmaceutical compounds, pesticides, dyes, surfactants, detergents, and personal care products (Li et al 2019 ). Antibiotics are one of the pharmaceutical compounds that are widely consumed either for treatment or prevention of diseases and/or infections, such as norfloxacin, sulfamethoxazole, ciprofloxacin, macrolides, and tetracyclines (Carneiro et al 2019 ).…”

The presence of emerging pollutants such as hazardous chemicals, pharmaceuticals, pesticides, and endocrine-disrupting chemicals in water sources is a serious concern to the environment and human health. Thus, this study focused on exploring the interaction mechanisms between ciprofloxacin (CIP) (antibiotic) and clay (a low-cost adsorbent) during sorption process. Acid activation technique was opted for modifying natural bentonite (NB) to enhance the adsorptive removal of CIP from water. The BET surface area analysis revealed that acid-activated bentonite (AAB) possessed more than two fold higher surface area as compared to NB. Combining pH zpc measurements, effect of solution pH and CIP speciation revealed that CIP sorption onto bentonite is highly dependent on solution pH. Kinetic studies confirmed that CIP sorption mechanism was chemisorption which included ion-exchange and surface complexation mechanisms. The mechanism of CIP sorption onto AAB was successfully explored with the assistance of characterization techniques. Maximal monolayer sorption capacity of AAB was found to be 305.20 mg/g, compared to 126.56 mg/g for NB. Reusability studies demonstrated that AAB could be reused successfully up to 5 cycles. Furthermore, column studies showed satisfactory results confirming that AAB can be successfully used in continuous mode for practical applications.

The present work provides a review focusing on contaminants of emerging concern (CECs) in aquatic environment, with an emphasis on their occurrence, monitoring, fate, and risk assessment in the research published in the scientific literature in 2019. Several studies revealed that these organic contaminants were detected in many water bodies and suspect, nontarget, and target screening provided an efficient detection for the co-existing organic substances with complex components. Wastewater resource recovery facilities were concurrently considered as a central source, and several specific chemicals have been found to be used as chemical markers to track the source of CECs in some urban watersheds. Reliable monitoring, reliable fate/toxicity assessment, and effective removal that consider CECs as a heterogeneous group rather than single substances will be the challenges for the research community in the future.
