Spectrophotometric determination of trace amounts of tellurium in hydrochloric acid solutions
Authors:
Abstract
Tellurium in the tetravalent state in hydrochloric acid solutions forms moderately strong complexes absorbing in the ultraviolet region. The spectrum consists of a number of bands characterizing various tellurium-containing particles. Solutions with a high HCl content (5–10 mol/L) and a low tellurium content (10⁻⁶–10⁻³ mol/L) possess buffering properties. The proportion of different forms of tellurium-containing particles depends little on the total concentration of tellurium and is determined by the concentration of hydrochloric acid.
