“…The results are in accordance with the study conducted by [64], wherein the TiO 2 -mediated photocatalytic degradation rate of aspirin showed an increasing trend with decreasing pH, which is similar to the present study [64]. Similar observations were reported in the study conducted over other acidic drug molecules [65,66].…”

In the present study, a magnetic nanocomposite based on biochar (BC) derived from sugarcane bagasse, nanoscale zerovalent iron (nZVI), and chitosan (CS) was fabricated to investigate its efficacy for the removal of two widely used pharmaceutically active compounds (PhACs), namely aspirin (ASA) and carbamazepine (CBZ). The synthesized nanocomposite (BC-CS@nZVI) was characterized using XRD, FTIR, and FESEM-EDX. The Response Surface Methodology–Central Composite Design (RSM-CCD) model was used for the optimization of removal efficacies for both drugs using five variables, i.e., adsorbent dose (0.05–0.1 g), pH (2–10), drug concentration (20–40 ppm), time (40–80 min), and temperature (40–60 °C). Under optimized conditions of adsorbent dose: 0.075 g, pH: 2, drug concentration: 30 ppm, time: 60 min, and temperature: 50 °C, the maximum removal efficiency of ASA drug was observed to be 97.8%, while in the case of CBZ drug under similar conditions with pH 6, the maximum removal was found up to 89.32%. The isotherm models revealed that both ASA and CBZ adsorption data fit well with the Langmuir isotherm showing monolayer adsorption. The kinetics of adsorption was well explained by the pseudo-first- and pseudo-second-order models in the case of ASA and CBZ, respectively. Thermodynamic parameters confirmed the feasibility of the reaction and its spontaneous and exothermic nature. The reusability and efficiency in water samples of the Ha’il region were investigated to demonstrate its potential for practical application.

“…The other preconditioning steps would include milling and sieving to ensure uniform size distribution of particles and repeatability during adsorption experiments. Following these preconditioning stages, the adsorbents can be used in adsorption of target compounds as pristine materials (Paredes‐laverde et al, 2018; Patil et al, 2019) or can be subjected to further treatment including chemical and/or physical modification prior to being used as adsorbents (Abdullah et al, 2022; Boushara et al, 2022; Lessa et al, 2018). Even though the preconditioning is good, it needs to be controlled and adjusted for a specific biomass material because the raw materials do not have the same physical structure and texture.…”

“…Hence, coffee and tea wastes are subjected to a preconditioning stage before chemical or physical modifications. The conditioning usually involves washing the waste materials in running tap water but some researchers have preferred to boil them in deionized water and followed by drying at 60–70°C overnight (Boushara et al, 2022; Patil et al, 2019). The boiling process ensures dissolution of salts and other soluble residues (Silva et al, 2018).…”

“…Even though this review covers a broad spectrum of pharmaceutical compounds, but from the data of adsorption performances compiled in Tables 1 and 2, it is evident that the optimum sample pH falls into three categories. The majority of the pharmaceuticals listed in Tables 1 and 2 had an optimum sample pH at weakly acidic conditions (pH 3–6) (Ahsan, Islam, Imam, et al, 2018, Ahsan, Jabbari, Islam, et al, 2018, Benyekkou et al, 2020, Boushara et al, 2022, S. Wong, Lim, et al, 2018), others at neutral pH (pH 7) (Khenniche et al, 2022; Nguyen et al, 2021, 2022) and another group at weakly basic range (pH 8–10) (El‐Azazy et al, 2021; He et al, 2021; Silva et al, 2020). Tetracycline (TC) for example, is an interesting pharmaceutical, which possesses three disassociation constants at pKa 1 = 3.3, pKa 2 = 7.8 and pKa 3 = 9.6 (Chico et al, 2012).…”

The introduction of large amounts of pharmaceuticals into the environmental waters is well‐documented in literature with their occurrence reported in all different water matrices accessible to humans and animals. At the same time, the increasing consumption of coffee and tea‐based beverages results in the generation of solid waste, which is mostly disposed‐off in the environment. To minimize environmental pollution, coffee and tea‐based materials have been proposed as suitable options to remove pharmaceuticals in environmental waters. Therefore, this article provides a critical review on the preparation and applications of coffee and tea‐based materials in removing pharmaceuticals from contaminated water. In this context, most studies in literature focused on the applications of these materials as adsorbents, while only limited work on their role in degradation of pharmaceuticals is discussed. The successful application in adsorption studies is attributed to high surface areas of adsorbents and the ability to easily modify the adsorbent surfaces by incorporating functional groups that provide additional oxygen atoms, which promote easy interactions with pharmaceuticals. Hence, the adsorption mechanisms are mostly described by hydrogen bonding, electrostatic and π–π interactions with sample pH playing a dominant role in the adsorption process. Overall, the present article focused on the developments, trends and future research direction on the preparations and applications of coffee and tea‐based materials for efficient removal of pharmaceuticals in water. Practitioner Points Review of tea and coffee wastes application for removal of pharmaceuticals in water Key applications in adsorption and degradation of pharmaceuticals in water Removal mostly explained by hydrogen bonding, electrostatic, and π–π interactions Trends, gaps, and future research to be explored are reviewed and highlighted
