Agave cocui vinasse was physicochemically characterized with reference to the relevant environmental regulations. The following results were obtained: COD: 71,000 mg.L-1, total solids: 21,000 dissolved 17,000 mg.L-1; pH: 4.06, conductivity: 9.45 mhoscm-1, Fe: 48.83 phenols: 8.66 BOD: 30,000 mg.L-1. Fenton and photo-Fenton reactions applied treat wastewater produced. For process, optimal oxidati...

Porous nanocomposites based on PrFeO3-TiO2 were synthesized using the glycine-nitrate combustion method with different values of mass content TiO2 (0–7.5 %) and subsequent heat treatment in air. The results X-ray phase analysis Raman spectroscopy confirmed presence ultradispersed TiO2, structurally close to that anatase. morphology, specific surface area, porous structure obtained powders chara...
