“…For instance, activated carbon from coconut shell achieved a specific surface area of 1108.4 m 2 g −1 , and pore volume of 0.4323 cm 3 g −1 , approximately 2 times larger than wood biochar (Herath et al 2019 ). Lach ( 2019 ) demonstrated that pores and surface area of activated carbons are directly proportional to their adsorption performance. Indeed, they found activated carbon with the largest specific surface of 1692 m 2 g −1 , and pore volume of 2.103 cm 3 g −1 exhibited the highest chloramphenicol adsorption capacity of 214.91 mg g −1 .…”

“…This fact increases the chance of contact between chloramphenicol and the absorbent, which also increases the removal efficiency (Chitongo et al 2019 ). For example, Lach ( 2019 ) investigated the removal efficiency of chloramphenicol by granular activated carbons. The outcomes proved that the maximum removal efficacy of chloramphenicol was 99% at a dose of 8 g L −1 , compared with 36% of that at a dose of 1 g L −1 .…”

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.

The pollution of surface and drinking water with pharmaceuticals is one of the growing problems. One of the groups used in large quantities involves nonsteroidal anti-inflammatory drugs which can be bought without a prescription. This group includes naproxen, which was identified in wastewater, surface water and even drinking water all over the world. The aim of the study was to assess the opportunities for the removal of naproxen sodium from water using carbon sorbents. The measurements were carried out for three commercial microporous (WG-12 and F-300) and micro-mesoporous (ROW 08 Supra) activated carbons. The kinetics and statics of adsorption were studied. The adsorption from solutions with pH from 6 to 10 and temperature from 20 o C to 40 o C was analysed. It was found that the higher the pH, the lower the adsorption and the higher the temperature, the greater the adsorption of naproxen sodium. The highest adsorption of naproxen sodium was obtained for the F-300 activated carbon, whereas the lowest-for the ROW 08 Supra activated carbon. It was found that the adsorption results depend on many factors, the most important of which include hydrogen bonds between carboxyl groups of naproxen sodium and phenolic groups on the surface of activated carbons and electrostatic repulsion between the anions of naproxen sodium and negatively charged the surface of the activated carbon. The results of adsorption kinetics were described with the following models: pseudo-first order and pseudo-second order, intraparticle diffusion, and Elovich. The highest values of correlation coefficient R 2 were obtained for the pseudo-second order and Elovich model. The results of adsorption statics were described using the Freundlich, Langmuir, and Temkin models. A good match between isotherms and the obtained results was obtained for the Freundlich and Temkin equations. It was found based on the adsorption intensity 1/n and distribution coefficient R L that this process was beneficial for all the considered activated carbons and the investigated adsorption conditions.

“…Studies have shown that the use of adsorption technique by activated carbon is very effective in the disposal of many organic pollutants such as dyes, pesticides and aromatic compounds generally (8) . However, there are two problems facing this promising technique: the first problem is the high production cost of activated carbon and needed for continuous regeneration process, in addition to the part loss of this material during each regeneration process, while the second problem relates to the difficulty of sediments disposal from the surface of activated carbon or other adsorbents (9) . This led the researchers to seek for other sources to be used as adsorbents or raw materials in the preparation of activated carbon from them and also so that the amount of remaining materials are small (10) .…”

Antibiotics are harmful pharmaceuticals to ecosystems in general and aquatic systems in particular. Therefore, its remediation from water bodies is a topic of great importance for water treatment and purification workers. This research investigates the removal of one of the most famous types of antibiotics, which was tetracycline from simulated synthetic aqueous solutions by adsorption technique using non-toxic, low cost and available agricultural waste which was pomegranate peels. The adsorption experiments were performed in adsorption laboratory unit of batch mode at different operating conditions and laboratory temperature. The operating parameters studied included pH of solution, dose of adsorbent media, treatment time, agitation speed and initial concentration of tetracycline. The results showed the ability of pomegranate peels to extract tetracycline from aqueous solutions with high efficiency of 81.55%. The results also showed that the percentage of antibiotic adsorption from aqueous solutions was inversely correlated with increasing the initial concentration and acidic function of the tetracycline solution while it was directly proportional to the amount of pomegranate peels, agitation speed and treatment time. In this style, one of the most important types of antibiotics that contaminated water was disposed of by a cheap material and using a simple, economical and environmentally friendly method accessing to the principle of zero residue level (ZRL).
