Speciation analysis of 129 I in seawater using coprecipitation and accelerator mass spectrometry and its applications
Speciation analysis of long-lived 129 I in seawater can provide useful information on the source of water masses. This paper presents an improved method for speciation analysis of 129 I based on coprecipitation of iodide as AgI with Ag 2 SO 3 and AgCl. By adding a small amount of 127 I carrier, the...

Summary: | Speciation analysis of long-lived 129 I in seawater can provide useful information on the source of water masses. This paper presents an improved method for speciation analysis of 129 I based on coprecipitation of iodide as AgI with Ag 2 SO 3 and AgCl. By adding a small amount of 127 I carrier, the separation efficiency of iodine species and the accuracy and precision of 129 I measurement are remarkably improved. 129 I species in depth profiles of seawater from the Antarctic were analyzed for investigation of water circulation in the Antarctic. |
