Environmentally Friendly UV-C Excimer Light Source with Advanced Oxidation Process for Rapid Mineralization of Azo Dye in Wastewater

ACS Omega, Год журнала: 2024, Номер 9(13), С. 15615 - 15632

Опубликована: Март 21, 2024

Wastewater discharged from the textile industry contains approximately 15% unfixed dyes, predominantly 60–70% azo dyes. These dyes are a major environmental concern due to their persistence and potential toxicity. In this paper, an environmentally friendly mercury-free XeI* excilamp emitting 253 nm UV light is reported, same has been utilized for degradation of using advanced oxidation process (AOP) with TiO2/H2O2. A new developed in which one electrode coated TiO2 nanoparticles that improves efficiency dye degradation. Additionally, effects varying loading concentrations, XeI*-excimer intensity, starting concentration, suspension pH, H2O2 addition examined. The outcomes study confirm 13 times faster XeI*-excimer/H2O2 than XeI*-excimer/TiO2, attributed abundance hydroxyl radicals generated by modified XeI*-excimer/H2O2. Also, RB5 2.3 as compared bare more 95% reduction chemical oxygen demand achieved 40 min case study, maximum energy yield 5712 mg/kWh reported. Furthermore, high degree found alkaline medium (pH 10). Because effluent highly alkaline, result significant, direct treatment possible. use source industrial applications appears be promising based on testing real wastewater matrix. treated its reusability agricultural purposes germination radish seeds soil, ∼26% enhanced observed wastewater.

Graphitic Carbon Nitride/CeO2 Nanocomposite for Photocatalytic Degradation of Methyl Red

Water, Год журнала: 2025, Номер 17(2), С. 158 - 158

Опубликована: Янв. 9, 2025

Nanosized ceria (CeO2) and a graphitic carbon nitride-loaded (CeO2/GCN) nanocomposite were synthesized using straightforward efficient method characterized by XRD, FTIR, SEM, TEM, TGA, BET analyses. These techniques confirmed that CeO2 was effectively supported on the surface of GCN, with particle sizes CeO2/GCN composite in range 10–15 nm pore size 3.33 nm. The photocatalytic activity NPs degradation methyl red dye under sunlight radiation studied UV–visible spectroscopy. A noticeable shift compared to pure suggests reduction its band gap energy, calculated at 3.90 eV for 2.97 nanocomposite. This enhances process, achieving removal efficiency 99.92% within short irradiation time 40 min nanocomposite, 69.47% NPs. findings indicate nitride significantly properties

Cross-Linked Organic Polymer with Amine/Dithiocarbamate Backbone: A Multipurpose Adsorbent for Removal of Dyes, Iodine, and Hg²⁺/Pb²⁺ from Wastewater

ACS Applied Polymer Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 7, 2025

The contamination of freshwater by industrial pollutants poses significant health risks, highlighting the urgent need for cost-effective, multifunctional materials to remove diverse environmental pollutants. Motivated pressing need, we have developed a class tertiary amine-centered dithiocarbamate (DTC)-based cross-linked polymers (CPs) fast and efficient removal from environment. Furthermore, subsequent synthesis, tunability side chain was achieved integrating two different types functional groups: CP-1, which contains benzyl (aromatic) group, CP-2, incorporates methyl (aliphatic) group. synthesized were characterized via various techniques including solid-state 13C NMR, FT-IR, TG-DTA, SEM, EDAX, DSC. polymeric employed dyes, radioactive iodine, heavy metals toxic mercury lead ions. CPs removed iodine water as well air with an inordinate uptake capacity >6.5 g/g vapor phase, demonstrating very high uptake. In line, benzyl-containing CP has azo dyes within 5 s capacities, i.e., 2315.46, 1138.01, 588.23 mg/g Eriochrome Black T, Congo Red, Methyl Orange, respectively. Moreover, material effectively eliminated metals, (Hg2+) (Pb2+), capacities 316.56 98.70 mg/g, also been successfully in column chromatographic purification contaminated practical application. Overall, DTC-based are versatile materials, showed facile both aliphatic aromatic moieties, thermal stability able few seconds followed implementation.
