An accurate and rapid procedure for the titrimetric determination of the rare earth metal ions by means of ethylenediamine‐tetraacetic acid is given. The titration is carried out in slightly acidic solution; a mixture of ammonium (or sodium) alizarinesulfonate + methylene blue is used as indicator.
