Aluminum trisoxinate

Virtually all chelate complexes of the type M(Ox)m derived from the cation Mm+ are extractable into chloroform and, being coloured, form the basis of spectrophotometric determinations. The extractions can be made more selective by controlling the pH (cf. Section 10.2.2.1) and/or by using suitable masking agents. Thus extraction of the yellow aluminum trisoxinate can be made almost specific at pH 8.5—9.0 if EDTA, cyanide ions and sulfite ions (to reduce FeI I to Fe11) are present. Since the range for extraction of individual metal oxinates extends from pH 1.6 to 14, separation of individual species is facilitated.52 59...
