Banaschik, Robert published the artcilePotential of pulsed corona discharges generated in water for the degradation of persistent pharmaceutical residues, Recommanded Product: Diatrizoic Acid, the main research area is pulsed corona discharge water degradation pharmaceutical residue; Advanced oxidation; Diclofenac; Ethinylestradiol; Hydroxyl radicals; Non-thermal plasma; Phenol.
Anthropogenic pollutants and in particular pharmaceutical residues are a potential risk for potable water where they are found in increasing concentrations Different environmental effects could already be linked to the presence of pharmaceuticals in surface waters even for low concentrations Many pharmaceuticals withstand conventional water treatment technologies. Consequently, there is a need for new water purification techniques. Advanced oxidation processes (AOP), and especially plasmas with their ability to create reactive species directly in water, may offer a promising solution We developed a plasma reactor with a coaxial geometry to generate large volume corona discharges directly in water and investigated the degradation of seven recalcitrant pharmaceuticals (carbamazepine, diatrizoate, diazepam, diclofenac, ibuprofen, 17α-ethinylestradiol, trimethoprim). For most substances we observed decomposition rates from 45% to 99% for treatment times of 15-66 min. Especially ethinylestradiol and diclofenac were readily decomposed As an inherent advantage of the method, we found no acidification and only an insignificant increase in nitrate/nitrite concentrations below legal limits for the treatment. Studies on the basic plasma chem. processes for the model system of phenol showed that the degradation is primarily caused by hydroxyl radicals.
Water Research published new progress about Acidification water pollution. 117-96-4 belongs to class isoquinoline, name is Diatrizoic Acid, and the molecular formula is C11H9I3N2O4, Recommanded Product: Diatrizoic Acid.
