Oxinates gravimetry

Gravimetry with Metal Oxinates 10,2.2.1 8-HydroxyquinoUne—metal complexes... 

The quantitative determination of metallic ions, which follows the precipitation as oxinates, may be carried out, depending on the case, by gravimetry (see Chap. 38) or by dissolution of the precipitate in hydrochloric acid and subsequent titration of oxine by bromometry (see Chap. 19). Moreover, in certain conditions, oxine is electroactive. As a result, it can be determined by amperometry.
