【摘要】：为了在线测量微生物燃料电池内溶解氧浓度,提高微生物燃料电池的产电效率,利用荧光猝灭原理,采用邻啡咯啉钌作为荧光标记物,并采用溶胶-凝胶法制备了氧敏感膜。将该敏感膜固定在塑料光纤表面,通过测量荧光指示剂发出的荧光强度实现了对溶解氧浓度的测量。实验结果表明,传感器的相对荧光强度与溶解氧浓度具有较好的线性关系,拟合系数达到0.980 7,且传感器具有良好的可逆性。
[Abstract]:In order to measure the concentration of dissolved oxygen in the microbial fuel cell and improve the efficiency of the microbial fuel cell, the oxygen sensitive membrane was prepared by sol-gel method by using o-Phenanthroline ruthenium as the fluorescent marker by using the principle of fluorescence quenching.The sensitive film was fixed on the surface of plastic fiber and the concentration of dissolved oxygen was measured by measuring the fluorescence intensity of the fluorescent indicator.The experimental results show that the relative fluorescence intensity of the sensor has a good linear relationship with the concentration of dissolved oxygen, the fitting coefficient is 0.980, and the sensor has good reversibility.
