Photometric Determination of Tantalum with Phenylfluorone
A photometric phenylfluorone method for the determination of traces of tantalum has been developed. The interference of other metals is eliminated by virtually isolating the tantalum by solvent extraction from hydrofluoric- hydrochloric acid solution with methyl isobutyl ketone and by masking with (ethylenedinitrilo) tetraacetic acid during the subsequent color development.
