A facile chemical procedure was utilized to produce an effective peroxy-monosulfate (PMS) activator, namely ZnCo2O4/alginate. To enhance the degradation efficiency of Rhodamine B (RhB), a novel response surface methodology (RSM) based on Box-Behnken Design (BBD) method employed. Physical and properties each catalyst (ZnCo2O4 ZnCo2O4/alginate) were characterized using several techniques, such as FTIR, TGA, XRD, SEM, TEM. By employing BBD-RSM with quadratic statistical model ANOVA analysis, optimal conditions for RhB decomposition mathematically determined, four parameters including dose, PMS concentration, reaction time. The achieved at dose 1 g l-1, dye concentration 25 mg time 40 min, efficacy 98%. ZnCo2O4/alginate displayed remarkable stability reusability, demonstrated by recycling tests. Additionally, quenching tests confirmed that SO4˙-/OH˙ radicals played crucial role in process.

Abstract Environmental contamination by hexavalent chromium (Cr(VI)) and antibiotic drug residues pose significant challenges to public health ecosystems. This study investigates the application of CoTiO 3 /BiVO 4 @MIL-Fe(53) (CT/BV@Fe-MOF) for reduction Cr(VI) degradation tetracycline (TCL) under visible light. After grafting an iron-based metal–organic framework MIL-Fe(53) on a modified composite, photogenerated electrons could easily be transferred from BiVO /Fe-MOF species via interfacial charge transfer. UV–vis diffuse reflectance spectroscopy showed that carriers were formed in response light absorption. The effect different operating parameters, including catalyst load, pH, initial Cr(VI), TCL concentration, was systematically evaluated during photocatalytic process. CT/BV@Fe-MOF composite exhibited 98.7% efficiency (50 ppm) 97.5% towards (30 within 90 min, resulting greater than pristine , Fe-MOF materials. displayed excellent stability over six cycles, highlighting its potential practical applications. In addition, plausible pathway using LC-ESI/MS analysis, while TEST program utilized investigate toxicity products generated

As a substitute for banned brominated flame retardants (BFRs), the use of organophosphate esters (OPEs) increased year by with increase in industrial production and living demand. It was inevitable that OPEs would be discharged into wastewater excess, which posed great threat to health human beings aquatic organisms. In past few decades, people used various methods remove refractory OPEs. This paper reviewed photocatalysis method, adsorption method wide applicability, biological mainly relying on enzymolysis hydrolysis degrade water. All three these had advantages high removal efficiency environmental protection organic pollutants. The degradation OPEs, mechanisms, conversion products were discussed summarized. Finally, development prospects challenges OPEs’ technology discussed.
