研制出一种利用高分子聚合物薄膜作为基底材料的光纤pH传感器,它是将刚果红染料试剂固定化到经化学处理过的高聚物薄膜上而制成的。实验中,运用了双臂反射传感方式和流动注射进样法。该传感器具有灵敏度高,牢固耐用,尤其是响应时间短(<0.03min)等特点。 A fiberoptic pH sensor using a polymer film as the base material has been developed, which is made by immobilizing the Congo red dye reagent onto a chemically treated polymer film. Experiments, the use of arms reflection sensing and flow injection injection method. The sensor has high sensitivity, robustness, especially response time is short (<0.03min) and so on.
