Abstract

Speciation analysis of long-lived 129I in seawater can provide useful information on the source of water masses. This paper presents an improved method for speciation analysis of 129I based on coprecipitation of iodide as AgI with Ag2SO3 and AgCl. By adding a small amount of 127I carrier, the separation efficiency of iodine species and the accuracy and precision of 129I measurement are remarkably improved. 129I species in depth profiles of seawater from the Antarctic were analyzed for investigation of water circulation in the Antarctic.
