Routine procedures of colorimetric determinations in the form of the oxyquinolinate in CCl/sub 4/ are described. The determination of Ge is carried out with phenylfluoron, that of De is made with quinalizarine; Nb is determined in the form of the Nb/sup 5+/ complex compound with thiocyanic acid; TA is determined with pyrogallol in an acid oxalate solution. Minor changes, introduced into the generally accepted methods, relate to the conditions of the decomposition of the test samples and the separation of elements being determined.
