Dual- Wavelength Spectrophotometric Determination of Properties of Titanium Complex Solution with o-Chlorophenylfluorone

Abstract

The ligand, o-chlorophenylfluorone (o-CPF) was sensitive to
complex titanium (Ti) at pH 6.0 and in the presence of triton x- 100.
The spectral correction principle was applied to the determination
of the characteristic factors of the complex instead of ordinary
spectrophotometry because of the interference of excess of
o-CPF. Results showed that the formed complex was expressed as
Ti(o-CPF)₃ and its cumulative stability constant was equal to
8.50 x 10¹⁶.
