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.
