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 use

New reactive azo dyes are described which are useful for optical determination of pH. The dyes are covalently linked (via ethylsulfonyl groups) to a novel type of transparent solid films consisting of a thin film of cellulose on top of a polyester support. The resulting membranes exhibit distinct co
