Background The high consumption of acetaminophen leads to high concentrations in surface water causing impacts on aquatic organisms, which is highlighting the need for investigation of alternative water and wastewater treatments. Therefore, the present study objective was to evaluate the adsorption capacity of acetaminophen onto Moringa oleifera Lam. seed husks after chemical and thermal treatment. Results The characterization of the adsorbent revelaed heterogeneous morphology with the presence of micro‐ and mesopores. Adsorption studies showed that the adsorption did not altered between pH 3 and 9, and that there was no significant effect of the ionic strength, indicating that the mechanism does not involve electrostatic interactions. In fact, Fourier transform infrard spectra showed that acetaminophen was adsorbed by hydrogen bonds and π‐stacking. The kinetic data were adjusted to the pseudo‐first‐order model, indicating an equilibrium time of 18 h. The equilibrium study showed that adsorption occurred in a monolayer and was favoured by the increase in temperature. The maximum adsorption capacity was 17.48 mg g−1, at 318 K, higher than some capacities found in the literature. The thermodynamic parameters indicated that the process was spontaneous, endothermic and physical. Conclusions The characteristics and results found compared to the recent literature verified the possibility of applying this residue as a low‐cost adsorbent for the removal of acetaminophen. © 2019 Society of Chemical Industry

“…CPPW potato peel waste carbon, CP commercial carbon a Data from Mestre et al (2014) In the pH range studied, sodium DCF is dissociated and so the species that will interact with the carbon samples presents negative charge. No studies were made at lower pHs because the solubility of DCF remarkably decreases due to the progressive protonation of the specie (pKa = 4) (Meloun et al 2007;Kincl et al 2004).…”

“…Biomass wastes, such as those generated in the agrofood industries, have been used as precursors of activated carbons and successfully applied to the removal of several pharmaceutical compounds (Baccar et al 2012;Cabrita et al 2010;Rovani et al 2014;Mestre et al 2014;ElShafey et al 2014). This constitutes a potential low-cost alternative in obtaining feedstock materials for adsorptionbased technologies, allowing at the same time the management of wastes, often without market value, through a high added-value valorization pathway.…”

In the present study, a novel porous carbon obtained by K 2 CO 3 activation of potato peel waste under optimized conditions was applied for the first time as liquid-phase adsorbent of sodium diclofenac in parallel with a commercial activated carbon. The biomass-activated carbon presented an apparent surface area of 866 m 2 g -1 and well-developed microporous structure with a large amount of ultramicropores. The obtained carbon presented leaching and ecotoxicological properties compatible with its safe application to aqueous medium. Kinetic data of laboratorymade and commercial sample were best fitted by the pseudo-second-order model. The commercial carbon presented higher uptake of diclofenac, but the biomass carbon presented the higher adsorption rate which was associated with its higher hydrophilic nature which favoured external mass transfer. Both adsorbents presented adsorption isotherms that were best fitted by Langmuir model. The biomass carbon and the commercial carbon presented adsorption monolayer capacities of 69 and 146 mg g -1 , and Langmuir constants of 0.38 and 1.02 L mg -1 , respectively. The better performance of the commercial sample was related to its slightly higher micropore volume, but the most remarkable effect was the competition of water molecules in the biomass carbon.

“…Among these methods, sorption on activated carbon is one of the most effective, economic and simplest methods for the removal of pollutants from aqueous solutions. Therefore, activated carbons are excellent adsorbents and promising materials that are extensively used in a wide range of applications such as medical uses [10], industrial applications [11], gas storage [12], catalysis [13] and environmental pollution. The activated carbon can be produced from various fossil carbon sources such as lignite, peat and oil residues, however the depletion of these resources encourages researchers to use renewable resources from biomass as precursors for activated carbons [14].…”
