Abstract : A optical fiber oxygen sensor for detecting dissolved oxygen in water has been fabricated by using Ru (bpy) 3Cl2 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 anti2disturbance ,better re2 peatability and stability. So it can monitor the changes of the concentration of dissolved oxygen in the water on line.
Key words : optical fiber oxygen sensor ; water quality monitoring ; phase lock2in amplifying ; fluorescence quenching ; dissolved oxygen
