The separation of iron(III)–edta, –methyl-edta, –dtpa, and –cdta was investigated by high performance liquid chromatography on silica-gel (ZORBAX SIL) and octadecyl-silica (ZORBAX ODS) columns. The chelates were retained on both columns from phosphate buffer mobile phase of pH 3, while the baseline separation was not achieved on the ODS column. The degree of increase in retention caused by the addition of tetrabutylammonium bromide to the eluent was greater on the ODS column than on the silica-gel column, and well separated chelates were eluted in the order, iron(III)–edta, –methyl-edta, –dtpa, and –cdta on both columns.
