Colorimetric and asid-base characteristics of pyrogallol red and
bromopyrogallol red
Abstract
Dissociation constants for pyrogallol red and
bromopyrogallol red have been determined
at ionic strength of 0,126-0,526 in 1,6% ethanol in water by spectrophotometric
and colorimetric methods. Molar absorptivity and molar coefficients of
colorimetric function was determined for individual forms of reagents.
The influence of the sulfonatingagenton the synthesis and ion-chromatographic properties of the sulfonated
poly(styrene-divinylbenzene) copolymers with high power of cross-linking
