Correlation between pH of medium and a tint a solid-phase indicator
Abstract
Colored solid-phase indicators are obtained by immobilization of organic dyes on styrenedivinylbenzene
(ST-DVB) and glycidyl methacrylate-divinylbenzene (GMA-DVB) copolymers. A color
scales which show a change of color depending on pH has been made by means of computer processing.
A digital codes of colors which were a basis for computer processing by method of regression analysis
has been made and it has allowed to receive the equation which connects physicochemical parameter of
рН with indices of color scale. The comparison of change of color of solid-phase indicators with their
soluble analog has been spent
