PHOTOELECTRIC MICRODETERMINATION OF IODATE AND IODINE

Photoelectric Microdetermination of Chloride in Biological Fluids, and of Iodate and Iodine in Protein-free Solutions

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 ...

Microdetermination 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...

Adsorption and desorption of iodine by various Chinese soils: II. Iodide and iodate

Rice (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...
