    Abstract:

    An extraction chromatographic method for determination of rare earths in minerals with P507 resin at pH 2-3 hydrochloric acid medium was stu4red. By using a mixture solutiop of ammonium chloride, ascorbic acid and sulfosalicylic acid as eluates, REE was determined with chlorophosphonazo-PN.
