The colorimetric indicator pararosaniline has been immobilized onto the cation-exchange resins Amberlite IRC-50, Dowex 50W-X8 and cellulose phosphate by electrostatic bonding. The reflectance of each reagent phase was measured using a bifurcated fibre-optic system and a flow cell. Pararosaniline immobilized
