Monitoring of Iodine Containing Degradation Products of X-ray Contrast Media Formed during Ozonation and UV Treatment
نویسندگان
چکیده
Iodinated X-ray contrast media (ICM) are benzene ring based organic compounds and designed to be very stable in human metabolism. Hence, they pass through the municipal wastewater system and are frequently found in wastewater treatment plant effluent [1, 2] and the receiving surface waters [3, 4]. Due to poor microbiological degradation, solar UV irradiation is important as a possible degradation pathway for ICM in surface waters [5].

Degradation of Organic Pollutant in Waste Water via CdMoO4 Nanostructures as an Effective Photocatalyst; Ultrasound-assisted Preparation and Characterization
Sphere-like cadmium molybdate (CdMoO4) nanostructures have been synthesized by a large scale and simple sonochemical method by using Cd(Sal)2 (Sal=salicylidene) and Na2MoO4.2H2O for the first time. The effects of sonochemical irradiation time, sonochemical power, temperature, solvent, surfactant and cadmium source were considered to obtain a controlled shape. The as-prepared nanostructured cadm...
متن کاملFormation of Stable Transformation Products of Pharmaceuticals in the Water Treatment Cycle
After human consumption, pharmaceutically active substances can be excreted and enter the effluent treatment facilities. Often degradation in sewage and water treatment and the environment is incomplete, resulting in the formation of transformation products. Within the Pharmas project (EU grant agreement no. 265346) three anticancer drugs were evaluated for the formation of stable transformatio...
متن کاملComparing the Efficiency of UV/TiO2 and UV/O3 Processes in Degradation of Sulfonamide Antibiotics in Aquatic Solution
Background and purpose: Emerging pollutants such as antibiotics are resistant to biodegradation. The aim of this study was to compare the effect of photocatalytic and Ozonation photolysis on decomposition of Sulfonamide antibiotics (Sulfacetamide, Sulfathiazole, Sulfamethoxazole, and Sulfadiazine) in aquatic environments. Materials and methods: In this study, experiments were conducted discont...
متن کاملDual-wavelength recording, a simple algorithm to eliminate interferences due to UV-absorbing substances in capillary electrophoresis.
Analytical interferences have been described due to the presence of various exogenous UV-absorbing substances in serum. Iodine-based X-ray contrast agents and various antibiotics have been reported to interfere with interpretation of serum protein pherograms, resulting in false diagnosis of paraproteinemia. In the present study, we have explored the possibility of measuring UV absorbance at two...

Nanocomposite of Ag/TiO2 and nanocrystalline TiO2 were prepared by using TiCl4 as a precursor in a simple sol-gel process. The prepared photo-catalysts were characterized by X-ray diffraction (XRD), scanning electron micrographs (SEM), energy dispersive X-ray microanalysis (EDX), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). A complete and effective photocat...
