✦ Synopsis

Abstract

A method for preparation of mercuri‐derivatives of fluorescein labelled by ^197^Hg or ^203^Hg from mercuric acetate and fluorescein has been described. Individual products formed in the reaction mixture were isolated with both paper chromatography and chromatography on alumina column. Their identification was carried out by determining the amount of mercury contained in individual chromatographic fractions. Polarographic observation of the overall mercurization reaction has shown that proceeds rather fast. Similar situation is also valid for exchange reaction between mercuricacetate‐^203^Hg and individual derivatives of fluorescein.
