A pH sensitive membrane based on Rhodamine B immobilized in a PVC membrane was prepared. The membrane is sensitive towards pH change of solution it contacted with due to the fluorescence spectral change of Rhodamine B in it. The membrane is sensitive towards pH in range from 2.0 to 4.0 in solution with response time ≤120 s and good reversibility, reproducibility and stability.
