| 中文摘要 | a phenolphthalein immobilized cellulose membrane for an optical ph sensor was described. the phenolphthalein was first reacted with the formaldehyde to produce a series of prepolymers with many hydroxymethyl groups. in this paper, the prepolymers was abbreviated to phenolphthalein-formaldehyde (ppf). then the ppf was covalently immobilized to the diacetylcellulose membrane via hydroxymethyl groups. finally the membrane was hydrolyzed in the 0.1 m naoh solution for 24 h to reduce the response time. advantageous features of the ph-sensitive membrane include (a) a large dynamic range from ph 8.0 to 12.50, or even broader, (b) rapid response time (2-30 s), (c) easy of fabrication, and (d) a promising material for determination of high ph values. the immobilized ppf has a broader dynamic range from 8.0 to 12.50 than the free phenolphthalein from ph 8.0 to 11.0, and this was due to the newly produced methylenes in our investigation. |
