  • A chromatographic method for separation of strontium from rubidium, using the unique alkaline-earth metal complexation ability of the carboxylic acids EDTA and DCTA is proposed. The method was developed in order to improve the effectiveness of 87Sr/86Sr isotope studies with ICP–QMS. Due to the isobaric overlap of 87Rb with 87Sr, strontium needs to be separated from rubidium prior to sample analysis with ICP–QMS. The method involves the retention of strontium, calcium, magnesium, and rubidium on… CONTINUE READING
