Spectrophotometric determination of thorium with 2,3,4-trihydroxy-2'-carboxy-5'-sulfoazobenzene

Spectrophotometric determination of thorium with 2,3,4-trihydroxy-2'-carboxy-5'-sulfoazobenzene.In this experiment, several chemicals are used like 7440-29-1 Gambarov, D. G.; Ayubova, A. M.; Yusubov, N. N.; Nguyen Chi Chy (Azerb. Gos. Univ., Baku, USSR). Azerb. Khim. Zh., (4), 131-5 (Russian) 1984. CODEN: AZKZAU. ISSN: 0005-2531.In this article, certain chemicals are used. One of their cas registry numbers is 7440-29-1 DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Section cross-reference(s): 68 Th(IV) was detd. in samples contg. Ca, Mg, and rare earth metals by photometry of its 1:2 complex with the reagent in a urotropin buffer (pH 3.0) at 490 nm. Beer's law was obeyed for 23-232 mg Th/25 mL. Properties of the reagent (dissocn. const., spectra) and the complex (instability const., spectra) were detd. ..
