摘要：

A method for producing membranes for optical pH sensors is described. The pH indicators (Neutral Red and Congo Red) are covalently bonded to a transparent acetylcellulose film. The membranes have good durability (> 9 months) and a short response time (ca. 30 s). The method is easy to perform and uses acetylcellulose as a carrier. The reagents for activating the cellulose support are inexpensive, non-toxic and widely available.
