“…7 Therefore, their removal from water environment is an important strategy for obtaining the sustainability of natural life. 8 Furthermore, since naproxen is classified in the priority list of Global Water Research Coalition and is widely detected at levels up to 2.3 mg L −1 in wastewater samples, 9 its removal from water samples is a significant issue of concern. For this reason, various removal methods have been applied.…”

BACKGROUND Low‐cost biosorbent (derived from peanut shells) with abundant oxygen‐containing functional groups can effectively adsorb the naproxen drug in solution. This study aimed to explore the main interactions responsible for adsorbing naproxen and develop several conventional methods for identifying primary adsorption mechanism. Some important operation parameters strongly effecting the adsorption process and mechanism were investigated and discussed. RESULTS A fast adsorption equilibrium can be reached at approximately 120 min. The Langmuir maximum adsorption capacity of biosorbent towards naproxen (Qomax; mg g−1) was 55.1 mg g−1. The study of adsorption thermodynamics indicated that the adsorption process was spontaneous (∆G° ≈ −21 kJ mol−1) and exothermic (∆H° = −14.9 kJ mol−1), and van der Waals force played an important role in the adsorption mechanism. Another important contribution of n–π interaction between the carbonyl groups on the biosorbent's surface and the aromatic rings in naproxen molecules was confirmed by Fourier‐transform infrared spectroscopy and a traditional method. Such n–π interaction cannot be well performed when carbonyl groups were oxidized into carboxylic groups under H2O2 treatment. Peanut shells exhibited an excellent adsorption capacity to various pollutants such as lead (Qomax = 167 mg g−1), cadmium (103 mg g−1), cobalt (88.8 mg g−1), diclofenac (56.1 mg g−1), and bisphenol A (24.5 mg g−1). CONCLUSIONS Simple methods were developed to identify the important role of van der Waals force and n–π interaction in the adsorption process of naproxen. Such methods might be applied to identify the similar adsorption mechanisms of other aromatic adsorbates onto other materials with similar properties. Peanut shells can serve as a promising biosorbent for eliminating naproxen and other pollutants from water environment. © 2020 Society of Chemical Industry

“…The data presented in this study shows that biochar produced from MMDM can be used to remove MB from water. MB has similar structural characteristics to some pesticides and pharmaceutical compounds containing benzene rings important for - interactions with the biochar, polar/ionic characteristics (Paunovic et al, 2019;Zhang et al, 2019), and functional groups capable of hydrogen bonds (Suo et al, 2019). It stands to reason that the adsorption of MB in this study can be used as an indicator for MMDM biochar's capability to remove other harmful organic compounds from water.…”

“…According to the model, if all the extension lines of the linear part do not pass through the origin, intraparticle diffusion is not the only rate‐limiting stage. [ 48 ] It is clearly seen that the cefdinir adsorption process was not only controlled by intra‐particle diffusion in both activated biochars (Figure 5d).…”

Cefdinir adsorption onto non‐activated biochar (WL‐BC) and activated biochars (WL‐BC‐H, WL‐BC‐OH) prepared from waste biomass (WL) is comparatively investigated in view of adsorption factors, adsorption isotherms and adsorption kinetics. Batch experiments are conducted to assess the effects of pH, adsorption time and initial antibiotic concentration. Various advanced techniques are applied to characterize the prepared biochars (BCs). Characterization of the new BCs reveal that the activation process do not have a significant effect on the chemical structure of activated carbons, but it increases the surface area up to eight times. The equilibrium data are simulated with the Langmuir adsorption model indicating monolayer adsorption for both activated biochars WL‐BC and WL‐BC‐H. However, the adsorption isotherm for WL‐BC‐OH is represented well by the Freundlich model, which shows that multilayer adsorption took place. The kinetic data are analyzed using various kinetic models. The maximum adsorption capacity of the activated biochar is approximately tenfold in comparison to the non‐activated biochar. Additionally, the real wastewater experiments with treated campus wastewater show that the adsorptive performance of the activated biochar is not affected by other ions. Consequently, BCs derived from defatted laurel leaves could be effective and eco‐friendly adsorbents for removing cefdinir from wastewater.
