百里香酚蓝光导纤维酸度传感器的研制

Thymol Blue Fiber Optic Acidity Sensor

将百里香酚蓝固定在Nafion膜上，以此为敏感膜研制的光导纤维酸度传感器，具有响应迅速可逆、稳定性好、选择性高的优点，适用于pH3．7～0范围酸度的传感监测及0．001-mol／L以上HF浓度的快速测定．

A fiber optic acidity sensor has been developed by using thymol blue absorbed on a nafion film. It possesses the advantage of rapid and reversible response with excellent stability and selectivity. The response range of this sensor is PH3.7-0. It is applied to the rapid determination of HF above 0.001 mol/L.
