¹²⁹I in 200-400 ml seawater

This method describes the radiochemistry of ¹²⁹I in seawater samples. It is based on the method described in Szidat et al (2000) and Michel et al (2012), modified during 2015 with own tests at EAWAG and ETH (Casacuberta et al., 2015). The method covers the radiochemistry of a seawater sample right after its collection to the final preparation of the cathode (target) before its measurement with Accelerator Mass Spectrometry (AMS).
