Abstract

The potential of phenylfluorone reagent solution for the development of optical pH sensor was discussed in this study. Phenylfluorone has been chosen because it has never been reported before for use in the development of optical pH sensor. Results from the study showed that a linear pH range for this reagent was pH 4-11. The colour changes were to yellow in strong acid, orange in both weak acid and weak base and purple in strong base. The colour change was within 5 seconds. Phenylfluorone has a good photostability with RSD value 4.2% for a study period of 95 days. The RSD values of the reproducibility study were found to be 2.60%, 0.9% and 1.4% for pH 2, pH 7 and pH 12, respectively. These observations indicate that phenylfluorone has a good potential for used as a sensing reagent for development of optical pH sensor.
