摘要
Neutron activation analysis combined with pretreatment based on anion-exchange was applied to the determination of Ir in the Bering Sea and Arctic Ocean seawaters. Separation and enrichment of Ir from seawater by a simple anion-exchange resin Bio-Rad AG1x8 was carried out prior to neutron activation. Ir concentrations in the vertically distributed Bering Sea and Arctic Ocean seawater samples were in range of 0.85-3.58 pg/l and 1.26-1.97 pg/l, respectively. The reagent blanks of the procedures were 0.42-0.60 pg Ir. It was found that Ir in the Bering Sea and in the Arctic Ocean displayed different types of vertical profiles.
