Interaction of Copper(II) and
Titanium(IV) with Pyrogallol Red and Bromopyrogallol Red in the Presence of
Surfactants
Abstract
Complexation of titanium(IV) and copper(II) with
pyrogallol red (PR) and bromopyrogallol red (BPR) in the presence cationic and
nonionic surfactants were studied by spectrophotometric and colorimetric
methods. Optimal conditions for the complexation and stoichiometry were
obtained. Molar absorption coefficients and molar chromaticity functions
coefficients of the complexes Ti(IV) and Cu(II) with PR and BPR were determined
in the presence of cetylpyridinium bromide and OP-7.
