FIELD: chemistry.
SUBSTANCE: invention relates to analytical chemistry and specifically to measurement of pH using chemical indicators. Method for investigating active reaction of a medium involves measuring colour-modified acid-sensitive textile materials from colour change, wherein acid-base dyes are firmly fixed on textile substrate by dyeing.
EFFECT: technical result is possibility of online monitoring of active reaction of medium for any control modes of pH-level, including continuous.
