Potassium Bromate Assay by Redox Titrimetry Using Arsenic Trioxide
Bromate, a disinfectant, is one of the analytes of interest in wastewater analysis. Environmental laboratories have a regulatory need for their measurements to be traceable to NIST standards. Bromate is not currently certified as a NIST Standard Reference Material (SRM). Therefore, a traceable assay of potassium bromate (KBrO3) is needed. KBrO3 was dissolved in water and assayed by redox titrim...
متن کاملArsenic trioxide
At an acute ingestion of arsenic trioxide, nausea, vomiting, diarrhea, and abdominal pain are early symptoms occurring within 30 min to several hours. Primary target organ is the gastrointestinal tract (GIТ), where hemorrhagic gastroenteritis can occur in serious cases. Among cardiovascular symptoms are tachycardia, ventricular fibrillation, and heart failure described. Neurological symptoms ca...
متن کاملToxicological Properties of Potassium Bromate
Potassium bromate (KBrO3), used in both the food and cosmetics industry, and a drinking water disinfection byproduct, is a nephrotoxic chemical and rodent carcinogen. As KBrO3 is primarily an oxidizing compound, reactive oxygen and other species generated from bromate have been held responsible for the genotoxic, carcinogenic and toxic effects. Bromate induces primary DNA oxidative damage, muta...
متن کاملProlongation of cardiac repolarization by arsenic trioxide.
Arsenic trioxide (As(2)O(3); ATO) has recently been found to be very effective for relapsed acute promyelocytic leukemia. Several articles reported prolongation of QT interval or ventricular arrhythmias in patients receiving ATO. However, the QT-prolonging effect has not been confirmed and the direct membrane effect of ATO has never been studied. In the present investigation, using conventional...
متن کاملNigella sativa fixed and essential oil modulates glutathione redox enzymes in potassium bromate induced oxidative stress
BACKGROUND Nigella sativa is an important component of several traditional herbal preparations in various countries. It finds its applications in improving overall health and boosting immunity. The current study evaluated the role of fixed and essential oil of Nigella sativa against potassium bromate induced oxidative stress with special reference to modulation of glutathione redox enzymes and ...
