3.Application
Pyrogallol possesses importance as a spectrophotometric reagent in the determination of niobium and tantalum. The absorptions of niobium and tantalum complexes are usually measured at 340 and 335 nm, respectively. The niobium complex is formed in slightly acidic medium, and the tantalum complex in strongly acidic medium (4 N HC1). The absorption spectra are pH-dependen.
