Abstract: Anew gel matrix for reagent immobilization was used to prepare three kinds of pH-fiber optic chemical sensors. The response time of the sensors is lower than 10 s, the pHtest and abrupt range is 1. 83~7. 54 and 1. 39~2. 97 respectively. The sensor generally has no reagent which comes off from it and can be used as long as the reagent is stable.
