“…Thus, several authors [147][148][149] in their intensive study of organic compound adsorption, proved that the process stays contentious, and noted that the two interactions (adsorbate-adsorbent) electrostatic and dispersive are involved in adsorption of aromatic compounds. However, Coughlin and Ezra, Yi et al, and Cunha et al [150][151][152] suggested that the adsorption of aromatic compounds onto activated carbon is based on the establishment of dispersion interactions between π electrons in the organic compound aromatic ring and π electrons of the activated carbon graphene planes (π-π interactions). Moreover, the more intense adsorption capacity of activated carbon was required in part to its weak oxygen content [153,154], thus a rise in its hydrophobicity and the electron density of the graphene planes [155,156].…”

The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa ) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.

“…Electron–donor–acceptor mechanism is a type of non-covalent interaction that an electron-rich π system can interact with a metal (cationic or neutral), an anion, another molecule, and even another π system (Yi et al 2020 ). Considering the uptake of chloramphenicol in the medium, π–π electron–donor–acceptor interactions can be considered as a main adsorption mechanism (Chen et al 2021 ).…”

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.

“…Compared to traditional materials, nanostructure adsorbents have exhibited much higher adsorption efficiency and faster adsorption rate in the treatment of wastewater. These characteristics render nano-adsorbents favorable for the sorptive removal of various organic compounds and heavy metal from wastewater (Shirmardi et al 2013;Hosseinzadeh et al 2018;Yi et al 2020;Zhao et al 2021).…”

The excellent properties of micro-nano materials and structures have attracted extensive attention especially in wastewater treatment. Based on this, magnetic multi-walled carbon nanotubes (MMWCNTs) have been prepared and used for the sorptive removal of five typical cationic dyes from aqueous solutions in the present study. Effects of several operational and environmental factors were investigated carefully, including initial pH values, common ions, contact time and temperature. The kinetics processes were well fitted by the pseudo-second-order kinetic model. The maximum adsorption capacities on MMWCNTs at 298.15 K for malachite green oxalate, auramine O, neutral red, crystal violet and rhodamine B were 442.2, 295.2, 183.4, 165.3 and 143.0 mg g−1, respectively. Differences in the size, structure and properties of these dyes led to the difference of adsorption amounts. ΔG0 were all negative within the temperature range tested, which meant the adsorption processes were spontaneous nature. Moreover, the adsorption processes of targeted dyes, except auramine O, were exothermic and entropy decreasing. The regeneration studies indicated that the MMWCNTs showed high reusability and the removal efficiencies can be achieved above 75% after four consecutive cycles. For the adsorption mechanism, electrostatic interaction, hydrogen bonds, π-π interaction together with hydrophobic interaction, could coexist during the adsorption process.
