STUDIES ON COLOUR REACTIONS OF COMPLEXES OF RARE EARTHS WITH ERIOCHROME AZUROL B, 5-NITRO-1, 10-PHENANTHROLINE AND CETYLTRIMETHYL AMMONIUM BROMIDE

<正> In our previous work, the colour reactions of quaternary complexes of rare earths with chromazurol S, 5-nitro-1, 10-phenanthroline (5-N-phen) and cetyltrimethyl ammonium bromide (CTAB) were reported. In this paper, the colour reactions of rare earths with eriochrome azurol B(ECB), 5-N-phen and C...03340-34
