Description
An improved method of separation of cosmogenic 10Be from soils and sediments has been developed. 10Be is either leached from samples with 6 M HCl, or if necessary, sediments are totally decomposed with HF and KF fusion. This paper concentrates on the latter. All of the iron, most of the aluminium and some titanium are complexed with EDTA and retained in solution during a series of Be(OH)2 precipitations. Remnant aluminium and beryllium are leached from the last titanium/aluminium/beryllium hydroxide precipitate with NaOH. A small cation exchange column in sulfate form is employed for the final purification of Be from Al and the overall yield is about 90 percents. 10 refs
