pH-sensitive optode membranes for detecting pH values in acidic media |
| 초록 |
To develop fluorescent optode membranes for pH measurement in strongly acidic media, a functionalized push-pull conjugate dye was synthesized and covalently immobilized on a HEMA-based polymer membrane (M1) and a silica sol-gel membrane (M2), respectively. Optode membranes M1 and M2 exhibited fluorescence emission and ratiometric absorbance changes in acidic pH range. The fluorescence intensities of the membranes increased with increasing pH. M2 has a wider pH response range but less sensitive to the pH change compared with M1. The immobilization of the dye and pH-sensing properties of the membranes will be presented. |
