Spectrophotometric determination of small amounts of tellurium in hydrochloric acid solutions
Authors:
Abstract
Tellurium in the tetravalent state in hydrochloric acid solutions forms moderately strong complexes that absorb in the ultraviolet region. The spectrum consists of a number of bands characterizing various tellurium-containing particles. Solutions with high HCl content (5-10 mol/l) and low tellurium content (10-6-10-3 mol/l) have 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.
