Spectrophotometric Titration of Telluric Acid

Abstract

As no direct, simple, and precise volumetric methods are available for the determination of telluric acid alone or in the presence of other acids, the possibility of a spectrophotometric titration was

The Oxides and Oxyacids of Tellurium

“…The ultraviolet absorption of tellurate ions at longer wavelength than telluric acid in solution allows the titration of telluric acid by ammonia to be followed spectrophotometrically (250-280 µ) with an accuracy of better than 1% (84).…”
