Rapid and efficient autoclave digestion for the extraction of iodine-129 from urine samples

The main goal of this paper is to provide a brief overview of the use and determination of 129I by means of the accelerator mass spectrometry. Although AMS is currently the most sensitive method for the determination of 129I, the preparation of target samples plays a key role in this method. The most commonly used methods are those in which iodine is lost due to elevated temperatures. Therefore, there is still room for effort to find the most suitable methods of preparation of iodine samples for measurement by the AMS method.

“…Due to the sensitivity of AMS, there is an opportunity to expand the use of 129 I applications into new fields such as biomedical applications or nutrition. Recently, (Awwadh, Cornett, and Herod 2021) study successfully extracted 129 I from human urine using hydrogen peroxide as a solvent. The concentration of 127 I and 129 I in their urine samples were significantly correlated and generally similar to the 129 I concentrations and 129 I/ 127 I ratios from environmental samples that are collected around the place of residency.…”
