FIELD: chemistry.
SUBSTANCE: method involves extraction of titanium (IV) from a solution containing cyanate ions, a complexing agent and an extraction agent with subsequent analysis of the extract, where the complexing agent and extraction agent used is a mixture of low-melting point diantipyryl methane and benzoic acid, taken in molar ratio 1:1. Extraction is carried out with H2SO4 acid content equal to 0.05-1.0 mol/l, with subsequent quantitative detection of titanium (IV) ions using a spectrophotometric method.
EFFECT: simplification and high selectivity, safety of extracting titanium ions for subsequent determination.
