Rhenium measurements on North Atlantic seaweed samples by ID-ICP-MS: An observation on the Re concentration factors

Abstract

The estimation of the Re concentration factor (CF) has been carried out to provide additional field information on the biochemical similarities between Re and Tc. Re concentration in brown seaweed samples from the North Atlantic Coast were measured using ID-ICP-MS. The chemical yields were quantitative, and the concentrations were distributed within a narrow range of 65 80 ng/g d.w. CF of Re was approximately 1.2.104 on average, i.e., one order of magnitude less than that found for 99Tc
