In this paper, a good conceal agent for titanium (IV) mandelic acid were the following aspects of research. 1. The order and structure of the mandelic acid complex of titanium (IV) were determined by the combination of extraction, chromatographic and polarographic methods; 2. Some of the complexes of titanium (IV) with mandelic acid were studied during the polarographic process Electrochemical behavior, including the relationship between the half-wave potential and pH, the reversibility of the polarographic complex polarographic wave and the electron transfer number of the electrode reaction, is proposed. Under the experimental conditions, the interaction between titanium (IV) and mandelic acid complex Of the electrode reaction: TiOX_2 + e + 2H ~ + (TiX_2) ~ + + H_2O (X on behalf of mandelic acid); 3 polarographic method has hitherto been reported Ti (IV) - mandelic acid complex The stability constants of the compounds were determined. Under the conditions of ionic strength of 0.2 M (KNO 3) and (25 ± 0.2) ℃, log K = 11.01 ± 0.42
