Iodine Sources - WIA - World Iodine Association

Today, no more than 2% of the total iodine consumption comes from this source. Some types of seaweed, particulary brown seaweeds of the Laminaria family, contain significant amounts iodine in the form of sodium and potassium iodide. Iodine concentration is variable, on average around 950 ppm in

Increasing contrast agent concentration improves ...

Three different concentrations of iodinated nonionic contrast material were used (300, 350, or 400 mg/mL). Total iodine dose (15 g) and injection rate (7 mL/s) were kept constant. There were 25, 53, and 19 patients in the different concentration groups, respectively; 5 patients were excluded due to uncorrectable motion artifacts.

Iodine Value - an overview ScienceDirect Topics

Iodine Value. The iodine value (IV) is a measure of total unsaturation of a lipid material. The standard method EN 14111 in the European biodiesel standard is based on the classic wet chemical method (Wijs) for determining the IV. It purportedly serves a similar purpose in EN 14214 as do the restrictions on methyl linolenate and fish oil esters.
