摘要： 以凝胶为基质的新型固定化试剂制备了3种pH荧光传感器.在实验条件下,其信号响应时间低于10s,pH突跃范围为1.83～7.54和1.39～2.97.基本上无试剂脱落,在试剂本身化学稳定期限内,具有一定的使用寿命.

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.
