摘　　要：用Ru(bpy) 3 Cl2 为指示剂 ,研制一种能用来测定溶解氧的光纤氧传感器。该传感器的响应时间小于 30s ,检测下限为 0 .5mg/L ,检测准确度为 0 .0 1mg/L ,并具有较强的抗干扰能力、较好的重复性和稳定性 ,可用于对环境水质的在线监测。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.
