Abstract

Using radiotracer solutions of Hg (203Hg) and Os (185Os), techniques have been developed for sampling these elements presumably suitable for ion probe measurements. Mercury has been electrodeposited on the cross-sectional area (∼5 mm2) of an electrochemically pure Cu wire giving a recovery ∼25 to 30% at the tip. Similar efficiency is found for Hg distillate solutions. Osmium has been collected in a Ni−NiS bead after loading its thiourea complex solution on filter paper. The recovery in the bead is 80–90%. These methods should be of help for isotopic study of these elements by ion microprobe. The suitability of these samples for measurements remains unconfirmed.
