“…Various experimental models were considered, in order to determine which one is suitable to describe the behavior of antibiotics adsorption. The vast majority of the consulted bibliography (Ismadji et al 2009;Ahmed y Theydan 2014;Yue et al 2014;Peñafiel et al 2019) make use of the Langmuir (Eq. 3) and Freundlich (Eq.4) non linear adsorption models.…”

“…Other authors have also regarded hydrophobia as being influential in the process (Peñafiel et al 2019). The structures of both sulfadiazine and trimethoprim feature two aromatic rings, while enrofloxacin and amoxicillin feature one aromatic ring and show a weaker adsorption over PAC.…”

“…Vegetal activated carbon can be produced from a variety of sources, including corncob, rice hulls, corn straw or date stones (Ahmed and Darweesh 2017;Liu et al 2017;Silva et al 2018;Peñafiel et al 2019). Among the various classification criteria apart from their origin, particle size is widely used to differentiate types of Activated Carbon (Lima et al 2016).…”

This study addresses the growing concern about the high levels of antibiotics in water, outlining an alternative for their removal. The adsorption of four representative antibiotics from commonly used families (fluoroquinolones, β-lactams, trimethoprim and sulfonamides) was performed over vegetal powdered activated carbon. The evolution of the adsorption was studied during 60 min for different initial antibiotic concentrations, not only individually but also simultaneously to determine competitive adsorption. Moreover, this research studied the adsorption isotherms and kinetics of the process, as well as the pH influence, FTIR of the Activated Carbon before and after adsorption was carried out. Trimethoprim and sulfadiazine showed more affinity for the adsorbent than amoxicillin and enrofloxacin. This trend might be attributed to their structure, capable of stablishing stronger π-π interactions with the adsorbent, which showed high affinity for the active sites of the adsorbent via FTIR. In addition, the sorption isotherms of the substances tested followed a Langmuir type isotherm, except for amoxicillin which presented similar fittings to both Langmuir and Freundlich isotherms. The antibiotics followed pseudo-second order kinetics.Sulfadiazine and amoxicillin gave better performances in acidic conditions. By contrast, the sorption of trimethoprim was favored in basic environments. Variations of pH had a negligible effect on the removal of enrofloxacin.

“…The performance of agricultural and industrial waste-based adsorbents for ECs removals depends on the type of ECs, modification of adsorbent material, and several external factors. Peñafiel et al, (2019) investigated ciprofloxacin removal by corn cob and rice husk-based adsorbent. The removals obtained by the corn cob was 56.3%, and rice husk was 59.7%.…”

This paper discussed the removal and the remediation of emerging contaminants (ECs) in water using adsorption and membrane filtration as a single and hybrid system. The classifications, sources, effects, detection techniques, and available technologies for ECs removal were discussed. Next, an overview of both adsorption and membrane filtration processes in terms of materials, separation mechanisms, factors affecting their performances, and their applications for ECs removals was provided. It was followed by a comprehensive review of the combination of the membrane and the adsorption processes with other physical, chemical, or biological treatments. Finally, progress in research on a hybrid system between membrane filtration and adsorption was discussed. The combination included adsorption as the pre-treatment, integrated adsorption/membrane filtration system, or adsorption as the post-treatment. Generally, the hybrid systems showed improved performance than a single system. Nonetheless, further studies are recommended for applications of those systems on a wide range of ECs removals and the scale-up issue.

Acetaminophen (ACT), an antipyretic analgesic, is one of the emerging pollutants that has been found in high concentrations in domestic and hospital wastewaters. This study 7the adsorption capacity of sugarcane bagasse (SB) and corn cob (CC) for the ACT removal through the dynamic simulation of the adsorption column using Aspen Adsorption® V10. The effects of flow rate (1.5–3.0 mL min− 1), ACT initial concentration (40–80 mg L− 1), and bed height (20–35 cm) on the breakthrough curves were studied. Finally, the simulation results were validated with experimental studies, and analyzed by error functions, sum of squared errors (SSE), absolute average deviation (AAD), and coefficient of determination (R2). Based on the predicted breakthrough curves, ACT is adsorbed in greater quantity on CC, with saturation times and adsorption capacity greater than SB in all simulations. The maximum adsorption capacity was 0.47 and 0.32 mg g− 1 for CC and SB, respectively, under condition of flow rate of 1.5 mL min− 1, bed height of 25 cm, and ACT initial concentration of 80 mg L− 1. Breakthrough and saturation times were higher when the column operated at low flow rates, large bed height, and low ACT concentrations, for both adsorbents. The predicted and experimental breakthrough curves satisfactorily coincided with R2 values greater than 0.97, SSE and AAD values less than 5% and 0.2, respectively, for all studies. The experimental adsorption capacity was greater for CC than for SB, thus confirming that the software is able to predict which adsorbent may be more effective for ACT removal. The results of this study would speed up the search for effective materials to remove ACT from wastewaters.
