Duan, Xiaodi published the artcileDecomposition of Iodinated Pharmaceuticals by UV-254 nm-assisted Advanced Oxidation Processes, Recommanded Product: Diatrizoic Acid, the main research area is decomposition iodinated pharmaceutical UV irradiation advanced oxidation wastewater; Diatrizoate; Hydrogen peroxide; Persulfate; Thyroxine; UV�54nm photolysis.

Iodinated pharmaceuticals, thyroxine (a thyroid hormone) and diatrizoate (an iodinated x-ray contrast medium), are among the most prescribed active pharmaceutical ingredients. Both of them have been reported to potentially disrupt thyroid homeostasis even at very low concentrations Here, UV-254 nm-based photolysis and photochem. processes, i.e., UV only, UV/H2O2, and UV/S2O82-, were evaluated for the destruction of these 2 pharmaceuticals. Approx. 40% of 0.5μM thyroxine or diatrizoate was degraded through direct photolysis at UV fluence of 160 mJ/cm2, probably resulting from the photosensitive cleavage of C-I bonds. While the addition of H2O2 only accelerated the degradation efficiency to a low degree, the destruction rates of both chems. were significantly enhanced in the UV/S2O82- system, suggesting the potential vulnerability of the iodinated chems. toward UV/S2O82- treatment. Such efficient destruction also occurred in the presence of radical scavengers when biol. treated wastewater samples were used as reaction matrixes. The effects of initial oxidant concentrations, solution pH, as well as the presence of natural organic matter (humic acid or fulvic acid) and alkalinity were also studied. These results provide insights for the removal of iodinated pharmaceuticals in water and/or wastewater using UV-based photochem. processes.

Wols, B. A. published the artcilePredicting pharmaceutical degradation by UV (MP)/H2O2 processes: A kinetic model, Recommanded Product: Diatrizoic Acid, the main research area is pharmaceutical photolysis water wastewater UV hydrogen peroxide kinetic model.

A kinetic model for the degradation of organic micropollutants (OMPs) by MP UV lamps was developed. The model includes (photo)chem. reactions of H2O2 and nitrate; reactions with the most important water matrix components; changes in pH; and transient radical concentrations Three pathways of organic micropollutant degradation are involved: direct photolysis, hydroxyl radical reactions and carbonate radical reactions. The model was validated using collimated beam experiments for a group of 35 pharmaceuticals in synthetic and natural water matrixes. For MP UV with 10 mg/L H2O2, good agreement between the modeled and measured degradation rates was found. For MP UV without H2O2, most of the pharmaceuticals were well predicted, except for the sulfonamides. A sensitivity anal. on different water matrix constituents was performed for MP UV with H2O2, NO3- and both H2O2 and NO3-. The most important chem. reactions for the degradation of OMPs are identified for different water matrixes.

Howard, Philip H. published the artcileIdentifying New Persistent and Bioaccumulative Organics Among Chemicals in Commerce, SDS of cas: 117-96-4, the main research area is identifying new persistent bioaccumulative organic chem.

This work identified com. chems. which may be persistent and bioaccumulative (P&B) and are not being considered in current Great Lakes, North American, and Arctic pollutant measurement programs. The authors combined the Canadian Domestic Substance List (DSL; a list of 3059 substances of unknown or variable composition complex reaction products and biol. materials) and the USEPA Toxic Substances Control Act Inventory Update Rule database for years 1986, 1990, 1994, 1998, 2002, and 2006, yielding a database of 22,263 com. chems. From that list, 610 chems. were identified by estimates from USEPA EPISuite software and using expert judgment. This work yielded some interesting, probable P&B chems. which should be considered for addnl. study. Recent studies, following initial reports and presentations on this work, confirmed the environmental presence of many of these chems.

Schulze-Hennings, U. published the artcileImproving vacuum-UV (VUV) photolysis of organic compounds in water with a phosphor converted xenon excimer lamp emitting at 193 nm, Computed Properties of 117-96-4, the main research area is vacuum UV photolysis organic compound ultrapure water effluent.

A novel vacuum UV excimer lamp emitting light at 193 nm was used to investigate the degradation of organic micropollutants in ultrapure water and wastewater treatment plant (WWTP) effluent. Overall, light at 193 nm proved to be efficient to degrade the investigated micropollutants (diclofenac, diatrizoic acid, sulfamethoxazole). Experiments with WWTP effluent proved the ability of radiation at 193 nm to degrade micropollutants which are hardly removed with commonly used oxidation technologies like ozonation (diatrizoic acid, EDTA, perfluorooctanoic acid, and perfluorooctanesulfonic acid).

Huebner, U. published the artcileOptions and limitations of hydrogen peroxide addition to enhance radical formation during ozonation of secondary effluents, Quality Control of 117-96-4, the main research area is hydrogen peroxide effluent ozonation radical formation.

The oxidation of secondary effluent with ozone and O3/H2O2 (peroxone) was evaluated in batch experiments as pre-treatment for soil aquifer treatment for non-potable reuse purposes. The addition of hydrogen peroxide improved the reduction of ozone-resistant compounds with an optimized radical formation at 0.5 mol H202/mol O3. However, the improvement of radical formation was shown to be limited to approx. 30-40% independent from ozone dosage. Also a preozonation step did not accelerate efficiency of subsequent peroxone treatment. Thus, other treatment options, such as an increase of ozone dosages, need to be considered for more efficient removal of ozone-resistant compounds, However, the peroxone process might still be a promising option for oxidation of bromide containing effluents, since a reduction of bromate formation can allow the application of higher ozone dosages.
