| 英文摘要 | An optical chemical pH sensitive membrane for optical chemical pH sensors has been developed by covalently immobilizing cresol red on optical transparent cross-linked polyvinyl alcohol (PVA) membrane surfaces by using acrylamide as couple agent and Fe(2+)/H(2)O(2) as initiator. The performance of the pH sensitive membrane was investigated. The results showed that the pH sensitive membrane had some excellent features. Firstly, the sensitive membrane still held two pH response intervals and the two response intervals were expanded from pH 0.15 -1.18 and pH 7.33 -8.94 of cresol red solution to 0.1 -5 mol/L [H(+)] and pH = 7.97 -12.26. Secondly, the optical chemical pH sensitive membrane had rapid response time (<25 s), good reproducibility, reversibility, excellent optical and storage stability. Lastly, the typical feature of the optical chemical pH sensitive membrane was easiness of fabrication. All of these show that the pH sensitive membrane is suitable to be used as a sensitive layer for optical pH sensor. |
