Amine-functionalized magnetic bamboo-based activated carbon adsorptive removal of ciprofloxacin and norfloxacin: A batch and fixed-bed column study

Fixed-bed column adsorption study: a comprehensive review

“…Peng and co-scientists had fabricated, characterized and utilized another adsorbents, amine functionalized magnetic-activated charcoal derived from bamboo wastes (AFM-BAC) and activated charcoal from bamboo wastes (BAC) for adsorption of fluoroquinolone antibiotics ciprofloxacin (CIP) and norfloxacin (NOR) through batch and column method. The saturated adsorption capacities of BAC and AFM-BAC were 172.5 mg/g and 293.2 mg/g for CIP and 193.4 mg/g and 315.7 mg/g for NOR, respectively (Peng et al 2017). Atenolol was removed using granular charcoal by Sancho (Sancho et al 2012) and Sotelo (Sotelo et al 2012), and their adsorption capacities were 51.10 and 44.36 mg/g, respectively.…”

In situ fabrication of hierarchical biomass carbon-supported Cu@CuO–Al2O3 composite materials: synthesis, properties and adsorption applications

“…The above result indicates that the NH 4 + -N adsorption is not only governed by the cation exchange process but also probably controlled by other processes; these include electrostatic interactions, planar aromatic structures, chemical bonding, hydrogen bonds, p-p electron donor-acceptor interactions, complexation and ion synergistic interactions and they are the most likely forces that contribute to the binding, which could be the adsorption mechanism interactions between the asprepared materials and NH 4 + -N that also contribute to controlling the NH 4 + -N adsorption on the as-prepared adsorbents from aqueous solutions. 12 The above four interactions synergistically contributed to the high adsorption capacity and removal efficiency for the NH 4 + -N adsorption on H-Cu-Al/BC (Scheme 1). As can be seen from Table S1, † H-Cu-Al/BC has abundant pores, which are composed of macro-, meso-and micro-pores to form a hierarchical porous structure.…”

“…[8][9][10] Up to now, some natural biomass materials such as bamboo, straw, bagasse, and corn cob have been applied to prepare carbon adsorbent materials for environmental applications. 11,12 Algae biomass are considered to be one of the most abundant plant wastes and it is readily available; its total world production is approximately 1.2 Â 10 4 t dry basis (about 1.6 Â 10 4 t wet basis) annually, which has continuously increased by an average rate of 10%. Furthermore, algae biomass grows widely in the oceans, seas and lakes, and its excessive growth can eventually lead to the signicant deterioration of water bodies.…”

Magnetic nano-biocomposite CuFe2 O4 @methylcellulose (MC) prepared as a new nano-photocatalyst for degradation of ciprofloxacin from aqueous solution

“…This antibiotic can be adsorbed in the sludge at a concentration of 42.2 mg/kg (8). In order to remove CIP and other antibiotics, various physical, chemical, and biological methods have been used, including membrane separation (9), ionexchange resin (10), nanofiltration (11), oxidation (12), and adsorption (13,14). In general, it can be said that most of these methods have not been cost-effective due to the lack of complete degradation of contaminants, as well as low efficiency, high cost of investment and management, and difficult maintenance (15).…”
