PHOTOMETRIC DETERMINATION OF SCANDIUM BY CHLOROPHOSPHONAZO III IN WOLFRAMITE (in Russian)

Journal Article · · Vestn. Mosk. Univ., Ser. II, Khim.
OSTI ID:4160458
An analysis of chlorophosphonazo III (2,7-bis(4 chloro2- phosphonbenzylazo)-1,8-dihydroxynaphthalene-3,6disulfonic acid) reaction with Sc and Th, Zr, Ti, Nb, Ta, U and other rare earths showed that they form a strong intracomplex compound. Absorbtion spectra of chlorophosphonazo-III with Sc and its complexes are given. The determination of Sc was carried out at pH 2 to 4 and reaction sensitivity of 0.1 to 0.2 g/ml. (R.V.J.)
