Carbamazepine (CBZ) is a pharmaceutical compound used in medical practice. Due to the ecotoxicological risk of its presence in the aqueous environment, researchers have been investigating its removal by adsorption technique. The aim of this study is to review the works done on the removal of CBZ from water by adsorption. Carbon‐based materials were the best types of adsorbent for CBZ uptake (> 200 mg g−1). Molecularly imprinted polymer (MIP) and carbon nanotubes (CNTs) showed especially good adsorption capacities. The key mechanisms of CBZ adsorption were π‐π interaction, electrostatic interactions, hydrogen‐bonding and hydrophobic interactions. Classical equilibrium isotherm models like Langmuir and Freundlich were always best‐fits and kinetics modelling was best‐fit to the pseudo‐second order model. The thermodynamics modelling of CBZ adsorption showed it was spontaneous and endothermic for most adsorbents. Methanol and acetone were especially effective for the desorption of CBZ from adsorbents and can achieve > 90 % removal even after 4–5 cycles. CBZ competes favorably in adsorption systems with other pharmaceutical species due to the advantages of the hydrophobic effect and molecular size.

“…141,177 Zhang et al 118 presented modified coal fly ash as a promising adsorbent of ciprofloxacin, claiming that the material is cheaper than other alternative adsorbents, such as clay minerals, and can offer relatively larger adsorption capacities. Swarcewicz et al 179 inspected a mixture of soil and coal fly ash for carbamazepine adsorption from water−ethanol solution. Batch assays showed that when the content of coal fly ash in the soil was beyond 30% the mean removed amounts of the pharmaceutical were higher than 92.8%.…”

Pharmaceuticals are environmental contaminants that have been widely detected in aquatic media. In this review, the occurrence of pharmaceuticals in the environment, its major causes, and implications along with effective procedures for their removal from contaminated water have been studied. Adsorption stands out as a promising treatment method, since it offers advantages such as lower energy consumption and simpler operation conditions in comparison to other tertiary treatments. Although commercial activated carbon is extensively studied as an adsorbent of pharmaceuticals, its large-scale application is limited by the high costs. Therefore, different nonconventional low-cost materials have been investigated and adsorbents based on clays, biochars, chitosan, agricultural and industrial wastes, and metal–organic frameworks have been addressed in many studies for pharmaceuticals uptake from water and wastewater. This article reviews key publications on this subject, discussing adsorption performance in terms of kinetics, equilibrium, thermodynamics, continuous fixed-bed process, regeneration capability, and historical, economical, and practical aspects.

“…Fly ash was also considered as an alternative adsorbent and fly ash-amended soil was investigated for its ability to remove CBZ from an aqueous solution (Swarcewicz et al, 2013). Results demonstrated a mean removal of 92.8% with a soil mixture containing 30% fly ash, while soil alone had only a 33% removal of CBZ, illustrating the mixture of fly ash and soil could be used as an adsorbent material for removing CBZ from water.…”

The goal of this review is to summarize new research published in the field of emerging pollutants in the past year. For the purpose of the review, unregulated and relatively new compounds found in wastewater, drinking water, recycled water and the environment were considered. The review consists of two parts, with Part I focusing on the occurrence of the contaminants in the media mentioned above, and Part II focusing on the treatment technologies.
