“…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].…”

“…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).…”
