DIAMMONIUM-5, 5'-INDIGO DISULPHONATE AS A REAGENT FOR THE GRAVIMETRIC DETERMINATION OF LANTHANUM, GADOLINIUM, AND YTTRIUM

OSTI ID:4719598
Lanthanum, gadolinium, and yttrium are quantitatively precipitated by diammonium-5, 5-indigo disuiphonate between pH 3.0 and 7.5 and the resulting complexes on ignition give the corresponding oxide, which can be weighed. Quantities as little as 4.75 mg of La/sub 2/O/sub 3/, 3.3 mg of Gd/sub 2/O/sub 3 and 4.2 mg of Yt/sub 2/O/sub 3/ can be thus determined. (auth)
