Abstract

An accurate spectrophotometric study on acid-base indicators immobilized by a silylation process is described. Immobilization modifies the acid-base properties of the indicators: a comparison with their behaviour in solution was made. Particular care was paid to the presence of hysteresis to the sensitivity and also to the peak wavelength. Early measurements performed with optical fibers were also described.
