Microdetermination of Chloride in Biological Fluids, with Solid Silver Iodate
was outlined in detail, with gasometric measurement of the iodate resulting from the reaction. In this paper titrimetric measurement of the iodate is described. Titrimetric measurement of the iodate is directly applicable to the supernatant fluid in the AgI08 precipitation of chloride from salt solutions, urine, serum, and protein-free jiltrate of serum and of whole blood.’ For the titrimetric ...
متن کاملMicrodetermination of Chloride in Blood Plasma and Cells, by Spectrophotometric Analysis Using Solid Silver Iodate.
As an extension of the silver iodate method of Sendroy,a convenient, reproducible, and sensitive method for analysis of chloride in 0.02-mi. samples of serum, whole blood, or red cells isdescribed. The procedureinvolves (1) preparation of a proteinfree filtrate of the sample, (2) Ag103 reaction with the filtrate, and (3) spectrophotometric analysisof iodineas the quantitative measureof the amou...

Background & Aims: A body of evidence indicates high prevalence of maternal iodine deficiency despite adequacy of nutritional iodine status in school age children as a reference population in West Azerbaijan province. Therefore, the present investigation was designed to evaluate the impact of oral iodine supplementation (150 µg/day in the form of potassium iodate) for three months co...
متن کاملSpectrophotometric Simultaneous Kinetic Determination of Iodide and Iodate Using Partial Least-Squares Calibration Method in a Single Kinetic Run
A rapid, sensitive and versatile kinetic method is presented for the simultaneous spectrophotometric determination of iodide and iodate by partial least-squares regression (PLS) using original and derivate data named as absorbance and rate data. The method is based on the catalytic effect of the cited anions on the reaction rate between Ce(IV) and As(III) in 2 mol l?1 sulfuric acid medium. The ...
متن کاملRice (Oryza sativa L.) roots have iodate reduction activity in response to iodine
Although iodine is not an essential nutrient for higher plants, their roots take up and transport the element. However, the exact mechanisms involved in iodine uptake and metabolism in higher plants have yet to be elucidated. In this study, we compared two cultivars differing in iodine tolerance ("Nipponbare" and "Gohyakumangoku") to increasing levels of I(-) and IO(-) 3 in the root solutions o...
