“…These results were explained by the initiation of a photo Fenton process and its synergy with existing oxidation processes in the oxidation medium. Similar effects for Fe 2+ on the degradation of t-butanol as a model water pollutant were recently reported [85].…”

“…The literature reported an increase in the oxidation and/or mineralisation rates of different water pollutants by photocatalytic ozonation when the concentration of ozone in water was increased [13,26,40,53,58,73,85]. However, some research groups reported a maximum effective ozone concentration for their photocatalytic ozonation setups, where higher ozone concentrations did not increase the oxidation or mineralisation rates and efficiencies considerably [12,83], as the concentration value depended on the characteristics of pollutants and their oxidation by-products in the oxidation matrix.…”

“…High‐cost techniques such as precipitation, membrane filtration, reverse osmosis, photocatalytic degradation, ion exchange, and advanced oxidation processes have been developed for the removal of antibiotics/other pharmaceutical residues and other organic pollutants from wastewater . These methods, however, require expensive equipment, high‐energy requirement, and/or continuous need of chemicals making them exorbitant and environmentally unfriendly .…”

The adsorption of amoxicillin (AMX), ampicillin (AMP), and chloramphenicol (CHLR) from simulated antibiotic‐contaminated water using adsorbents prepared from grape slurry waste is studied. Batch adsorption experiments are carried out to evaluate the adsorption capacity of the adsorbents for AMX, AMP, and CHLR. Adsorption isotherms are described by the Langmuir and Freundlich isotherms, while the pseudo‐second order kinetics describe the sorption processes. Negative values of the enthalpy change show that the sorption processes are exothermic, and the positive values of the Gibbs free energy change indicates non‐spontaneous but feasible nature of the adsorption. The study shows that grape slurry waste could be a good precursor to prepare effective adsorbents for the remediation of antibiotic‐contaminated wastewater.

The sorption of methylene blue (MB) and basic yellow 28 (BY28) dyes in water on Ag@ZnO/MWCNT (Ag‐doped ZnO loaded on multiwall carbon nanotubes) nanocomposite is investigated in a batch process, optimizing starting initial dye concentration, sonication time and adsorbent mass. Isotherms and kinetic behaviours of MB and BY28 adsorption onto Ag@ZnO/MWCNT were explained by extended Freundlich and pseudo‐second‐order kinetic models. Ag@ZnO/MWCNT was synthesized and characterized using X‐ray diffraction, energy‐dispersive X‐ray spectroscopy, field emission scanning electron microscopy and Brunauer–Emmett–Teller analysis. According to the experimental data, adaptive neuro‐fuzzy inference system (ANFIS), generalized regression neural network (GRNN), backpropagation neural network (BPNN), radial basic function neural network (RBFNN) and response surface methodology (RSM) were developed, and applied to forecast the removal performance of the sorbent. The influence of process variables (i.e. sonication time, initial dye concentration, adsorbent mass) on the removal of MB and BY28 was considered by central composite rotatable design of RSM, GRNN, ANFIS, BPNN and RBFNN. The performances of the developed ANFIS, GRNN, BPNN and RBFNN models were compared with RSM mathematical models in terms of the root mean square error, coefficient of determination, absolute average deviation and mean absolute error. The coefficients of determination calculated from the validation data for ANFIS, GRNN, BPNN, RBFNN and RSM models were 0.9999, 0.9997, 0.9883, 0.9898 and 0.9608 for MB and 0.9997, 0.9990, 0.9859, 0.9895 and 0.9593 for BY28 dye, respectively. The ANFIS model was found to be more precise compared to the other models. However, the GRNN method is much easier than the ANFIS method and needs less time for analysis. So, it has potential in chemometrics and it is feasible that the GRNN algorithm could be applied to model real systems. The monolayer adsorption capacity of MB and BY28 was 292.20 and 287.02 mg g−1, respectively.
