The investigation of renal function in health or disease demands a reliable method for the estimation of diodone in blood and urine. The methods of Alpert (1941), Flox, Pitesky & Alving (1942), Corcoran & Page (1943) all involve the use of bromine to split iodine from the diodone molecule and to convert this into iodate. Having had a fairly wide experience in the use of diodone in the estimatio...

This paper describes a sensitive spectrophotometric method developed for determination of Ketoconazole (KC) in tablets based on amplification reactions. Ketoconazole was oxidized with periodate, resulting in formation of KC2+ and iodate ions. After masking the excess periodate with molybdate, the iodate was treated with iodide to release iodine. The liberated iodine was transformed to [Formula:...

Since iodine readily sublimes at ambient temperature, the effectiveness of salt iodization programs depends on the stability of the iodine carrier, typically potassium iodate. We examined the stability of iodine in typical salts available in 12 countries in a controlled laboratory setting, at high temperature (40°C) and controlled humidity (60 or 100%) for periods up to 12 months. Iodine was ra...

In 1950, a quarter of a century after his first-ever nonlinear optical experiment when intensity-dependent absorption was observed in uranium-doped glass, Sergey Vavilov predicted that birefringence, dichroism and polarization rotatory power should be dependent on light intensity. It required the invention of the laser to observe the barely detectable effect of light intensity on the polarizati...

Planktic foraminifera test iodine to calcium ratios represent an emerging proxy method assess subsurface seawater oxygenation states. Several core-top studies show lower planktic I/Ca in locations with oxygen depleted waters compared well oxygenated environments. The reasoning behind this trend is that only the oxidized species of iodine, iodate, incorporated foraminiferal calcite. calcite thou...
