| Abstract: | A optical fiber oxygen sensor for detecting dissolved oxygen in water has been fabricated by using Ru(bpy)_3Cl_2 as the indicator. The sensor's response time is less than 30 s. It has the detecting limit of 0.5?mg/L and the detecting precision of 0.01?mg/L.Moreover,the sensor has strong ability of anti-disturbance,better repeatability and stability.So it can monitor the changes of the concentration of dissolved oxygen in the water on line. |
