“…The same strategy of evaluating individual effects of ions to prove the role of the natural water matrix has been utilized by Camargo-Perea et al [40] . The sono-degradation of the antibiotic sulfacetamide exhibited similar profiles in mineral water and distilled water with HCO 3 – (at the same concentration presents in the mineral water) [40] . In turn, Merouani et al [54] have assessed the effect of bicarbonate alone and bicarbonate combined with sulfate (another anion highly concentrated in mineral water) during the sono-degradation of the dye rhodamine B.…”

Highlights Sonodegradation of organic pollutants in ions-rich matrices is critically reviewed. Ultrasound is able to degrade pollutants of diverse nature in ions-rich matrices. Low concentrations of contaminants favor degradation in mineral water and seawater. Efficient pollutants sonodegradation in mineral water or seawater but action in urine is limited. Ecotoxicity and transformations after ultrasound action on matrices must be tested.

“…In the same time the wastewater plants encounter significant difficulties to address the increase of contaminants concentration and structure [2][3][4]. Among these contaminants, the organic pollutants such as phenols [5], pesticides [6], pharmaceutical [7] and dyes [8] raise special issues due to their impact on human health and aquatic life. The organic pollutants removal by conventional methods (adsorption, coagulation, filtration, microorganism and enzymes) showed important limitation due to the reluctance of these molecules [9,10].…”

The organic pollutants removal by conventional methods (adsorption, coagulation, filtration, microorganism and enzymes) showed important limitation due to the reluctance of these molecules. An alternative to this issue is represented by the photocatalytic technology considered as an advanced oxidation process (AOP). The photoreactors design and concepts vary based on the working regime (static or dynamic), photocatalyst morphology (powders or bulk) and volume. This mini-review aims to provide specific guidelines on the correlations between the photoreactor concept characteristics (working regime, volume and flow rate), irradiation scenarios (light spectra, irradiation period and intensity) and the photocatalytic process parameters (photocatalyst materials and dosage, pollutant type and concentration, pollutant removal efficiency and constant rate). The paper considers two main photoreactor geometries (cylindrical and rectangular) and analyses the influence of parameters optimization on the overall photocatalytic efficiency. Based on the systematic evaluation of the input data reported in the scientific papers, several perspectives regarding the photocatalytic reactors' optimization were included.

A notable level of apprehension exists over the adverse impacts of dye pollution on aquatic ecosystems and human well‐being. The primary objective of this research is to assess the effectiveness of Fenton catalytic reactions in degrading 14 different commercial azo dyes (both single and double) present in aqueous solutions. The investigation focused on the function of dye structures, using a combination of experimental data and examination of theoretical factors. Dye degradation process was carried out at pH 3, and the concentrations of Fe2+ (10−4 mol/L), H2O2 (2 × 10−3 mol/L), and dye (0.05 g/L). The findings revealed that dyes with a larger molecular weight were more effective at degrading (D%), with the overall degradation efficiency varying from 0% to 94%. Functional groups played an important role in degradation efficiency; for example, dyes with higher aromatic rings led to less D%, while a higher number of sulfonic, methyl, and nitro groups was responsible for better D%. Notably, the presence of OH groups in the backbone of dyes (AB 24, ABE 113, and MB 9) formed the Fe complex during the catalytic process, and the D% was minimal. On the other hand, theoretical quantum calculations such as the greater the JCLogP, highest occupied molecular orbital, and Dipole moment value, the higher the degradation efficiency. And dyes with low lowest unoccupied molecular orbital tended to have a better degradation efficiency. To some extent, UV–Vis spectral analysis was investigated to determine the degradation pathway, and the pseudo‐second‐order kinetic model fitted better in the degradation process. The overall experimental and theoretical findings suggested that dye degradation efficiency by the Fenton process is structure‐dependent.Practitioner Points Insights into the role of azo dye structures‐properties on degradation efficiency. Higher molecular weight and sulfonic groups containing dyes showed better degradation efficiency. Hydroxyl groups play the formation of the Fe complex during the degradation process. Higher values of HOMO and lower values of LUMO enhanced degradation efficiency. The pseudo‐second‐order (PSO) kinetic model obeyed the Fenton process.
