Abstract

The complexation of titanium (IV) with 2-hydroxy-5-tret-butylphenol-4’-methoxyazobenzene was studied using atomic-absorption and spectrophotometric methods. Optimum conditions were found for the formation of a complex and its extraction with chloroform and n-butanol which provide necessary fixation efficiency of titanium ions. Stability constants of the complex 02±0,01, as well as equilibrium constant of complexation reaction (3,52·104) were calculated using Komar method. Molar absorption coefficient equals to ( (3,2-4,1) 104. Calibration curve is linear at concentrations of 1-10 mcg/ml. Extraction-atomic adsorption determination of titanium was developed.

Keywords: Titanium, complexation, extraction, atomic-absorption technique
