DETERMINATION OF RARE EARTH ELEMENTS FROM PHOSPHORIC ACID SOLUTION

Comparative characterization methods for the determination of REE in phosphoric acid solution was made. It is shown that the definition of total REE possible by spectrophotometry with Arsenazo III. Using mass spectrometry with inductively coupled plasma is the best method to identify individual REE. Atomic absorption method is inappropriate to use when the content in the solution is not more than three REE.
