Sulfadiazine, sulfamethazine and sulfachloropyridazine removal using three different porous materials: Pine bark, “oak ash” and mussel shell

Efficacy of Different Waste and By-Products from Forest and Food Industries in the Removal/Retention of the Antibiotic Cefuroxime

“…In the case of tetracyclines, a high adsorption capacity was also obtained for wood ash, with pine bark also showing a high capacity to retain tetracyclines (unlike what was observed in the present study for CFX and pine bark), while the mussel shell was not suitable for the removal of these substances. Regarding the results of sulfonamide adsorption on those materials, Conde-Cid et al [36] also obtained results showing differences in relation to the current work, with pine bark retaining practically 100% of the added sulfonamide, while wood ash and mussel shell were not effective in retaining these antibiotics.…”

“…For three of the materials used in this study (wood ash, pine bark, and mussel shell), Conde-Cid et al [35,36] studied in previous works their adsorption capacity for three tetracycline antibiotics (oxytetracycline, chlortetracycline, and tetracycline) and for three sulfonamides (sulfadiazine, sulfamethazine, and sulfachloropyridazine). In the case of tetracyclines, a high adsorption capacity was also obtained for wood ash, with pine bark also showing a high capacity to retain tetracyclines (unlike what was observed in the present study for CFX and pine bark), while the mussel shell was not suitable for the removal of these substances.…”

“…For the former, Conde-Cid et al [35] also obtained a low desorption from wood ash, but (unlike what was observed in the present study with CFX) these authors found that pine bark adsorbed tetracyclines in a way that was practically irreversible, while desorption from mussel shell was high (up to 44% of what was adsorbed). In the case of sulfonamides, Conde-Cid et al [36,50] (2021, 2020) reported that only pine bark retained irreversibly high concentrations of these antibiotics, while wood ash and mussel shell had a low adsorption capacity and desorbed a high percentage of what was previously retained.…”

Application of Water Hyacinth Biomass (Eichhornia crassipes) as an Adsorbent for Methylene Blue Dye from Aqueous Medium: Kinetic and Isothermal Study

“…The study of MB desorption with stem and leaf bioadsorbents is important for the material to be reused again in the adsorption process [36,77]. The adsorption, desorption, and reuse experiments (first, second, and third times) were performed and described in the methodology.…”

Removal of sulfanilamide by tailor-made magnetic metal-ceramic nanocomposite adsorbents

“…They can also deteriorate the quality of drinking water and may cause potential hazard (carcinogenicity, teratogenicity and mutagenicity) (Qin et al, 2020). Recently, antibiotics have been detected in natural waters at concentration levels going from ng/L to µg/L (Sabri et al, 2020;Zhou et al, 2019;Conde-Cid et al, 2021;Dekhi-Bemani et al, 2021). For this reason they have been declared as priority substances in water protection policies (Directive 2013/39/EU), Several technologies have been developed to remove these contaminants such as coagulation, sedimentation, advanced oxidation processes, filtration, membrane technologies, and biological treatments (Ortiz et al, 2015;Kassinos et al, 2011;Pirozzi et al, 2020;Sannino et al, 2014;Sannino et al, 2015).…”
