Interaction
of molybdenum(VI) with pyrogallol red and bromopyrogallol red in the presence
of surfactants
Abstract
Complexation
of molybdenum(VI) 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 Mo(VI) with PR and BPR
were determined in the presence of cetylpyridinium bromide and OP-7.
