“…The adsorption of CAP on AC that was described by a pseudo second-order kinetic model implied a chemical controlling step, indicating the reactions involved valency forces via sharing or exchanging electrons between the surface functional groups on AC and CAP molecules [39]. Similar observations on adsorption kinetic for other carbon materials have been reported in the literature [24,40,41]. Qin et al [40] suggested that chemical adsorption was the rate-controlling step of CAP adsorption on porous carbon because the kinetic data fitted a pseudo-second-order kinetic model.…”

“…The samples were shaken at 25 • C and 120 rpm in a thermostated shaker bath (model THZ-82B, Jintan Medical Instrument Factory, Jintan, China) for 48 h to ensure adsorption equilibrium. After equilibrium, the samples were filtered through a 0.45-µm membrane filter, and the concentration of CAP in the filtrate was analyzed by a UV-vis spectrophotometer (UV-5100, Shanghai Metash Instruments Factory, Shanghai, China) at a maximum wavelength of 278 nm [24].…”

“…Fan et al [26] reported a value of 3 mg/g for CAP adsorption capacity by NaOH-modified BC, and Sun et al [22] estimated CAP adsorption capacity of modified kaolinite of only around 0.59 mg/kg. As a promising porous carbonaceous adsorbent, activated carbon has demonstrated an extraordinary adsorption capacity for removing various antibiotics due to its large surface area and highly developed pore volume [18,24,27]. Mohd Din et al [24] found mesoporous carbons produced by a hard-templating method have a maximum adsorption capacity of CAP of around 209.7 mg/g.…”

“…Adsorption, due to its simplicity and eco-friendliness, is an effective method for antibiotic removal from aqueous solution [18,19]. Porous materials have been used in CAP adsorptive removal, such as mesoporous silica, carbon nanotubes (CNTs), earth materials, bamboo charcoal (BC) and mesoporous carbon [20][21][22][23][24]. Although mesoporous silica and CNTs showed high CAP adsorption capacities, they exhibited potential toxicity, complex fabrication process and high cost ($120-180 per kilogram of CNTs) [23,25].…”

Low-cost and efficient activated carbon (AC) was prepared from Typha orientalis via phosphoric acid activation for chloramphenicol (CAP) removal. The adsorption capacity and mechanisms of CAP on AC were investigated. The physicochemical properties of AC were characterized by an N 2 adsorption/desorption isotherm, elemental analysis, Boehm's titration and X-ray photoelectron spectroscopy (XPS). The effects of experimental parameters were investigated to study the adsorption behaviors of CAP on AC, including contact time, initial concentration, ionic strength, and initial pH. AC had a micro-mesoporous structure with a relatively large surface area (794.8 m 2 /g). The respective contents of acidic and basic functional groups on AC were 2.078 and 0.995 mmol/g. The adsorption kinetic that was well described by a pseudo-second-order rate model implied a chemical controlling step. The adsorption isotherm was well fitted with the Freundlich isotherm model, and the maximum CAP adsorption capacity was 0.424 mmol/g. The ionic strength and pH had minimal effects on CAP adsorption. The dominant CAP adsorption mechanisms on AC were evaluated and attributed to π-π electron-donor-acceptor (EDA) interaction, hydrophobic interaction, in conjunction with hydrogen-bonding interaction. Additionally, AC exhibited an efficient adsorption performance of CAP in a realistic water environment.

Chloramphenicol is a broad-spectrum bacterial antibiotic used against conjunctivitis, meningitis, plague, cholera, and typhoid fever. As a consequence, chloramphenicol ends up polluting the aquatic environment, wastewater treatment plants, and hospital wastewaters, thus disrupting ecosystems and inducing microbial resistance. Here, we review the occurrence, toxicity, and removal of chloramphenicol with emphasis on adsorption techniques. We present the adsorption performance of adsorbents such as biochar, activated carbon, porous carbon, metal–organic framework, composites, zeolites, minerals, molecularly imprinted polymers, and multi-walled carbon nanotubes. The effect of dose, pH, temperature, initial concentration, and contact time is discussed. Adsorption is controlled by π–π interactions, donor–acceptor interactions, hydrogen bonding, and electrostatic interactions. We also discuss isotherms, kinetics, thermodynamic data, selection of eluents, desorption efficiency, and regeneration of adsorbents. Porous carbon-based adsorbents exhibit excellent adsorption capacities of 500–1240 mg g −1 . Most adsorbents can be reused over at least four cycles.
