Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: The advanced oxidation technology of using ultrasound enhanced zero-valent iron/potassium persulfate can effectively remove carbamazepine antibiotic organic contamination wastewater, with ultrasound playing a key role in improving the efficiency of the reaction and expanding the pH range for CBZ degradation. The mechanism involves the generation of active radicals such as SO4·−, (OH)·, and O2(·−) which contribute to the removal of CBZ, with SO4·− playing a prominent role. The degradation process is promoted by the dissolution of iron powder, production of Fe2+ ions, and activation of S2O82- to produce sufficient SO4·− radicals, leading to the efficient degradation of CBZ.
