Bis-(1’-phenyl-3’-methyl-5’-oxopyrazol-4’-yl)-phthaldione, an acyclic β-diketone type quadridentate chelating agent, was synthesized for the first time by the aμthors. Due to the ferro-philic and rock-philic geo...
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, th...
Continuing the series of investigation on the use of four component complexes in spectrophotometric trace determination of rare earth elements, it was found that rare earth elements (RE) formed soluble green complexes...
