Abstract
UO22+ reacts in aq. solns. with Methylthymol Blue (I) to give 1:1 and 2:1 complexes and Th4+ reacts with I to give 1:1, 2:1, and 1:2 complexes. The complexes were studied spectrophotometrically and their molar absorptivities at selected wavelengths (530-600 mm) and complex formation consts. are given. The dinuclear complexes absorb at a higher wavelength than the mononuclear complexes. Dinuclear complex formation depends on acidity and soln. compn. Structures of these complexes are proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
