摘要
以天然海水作为电解质,利用荧光显微镜、扫描电镜等表征方法和开路电位、恒电位极化等电化学测试手段研究了生物膜附着与电极表面电位的相互影响。结果表明:(1)生物膜在电极表面的附着导致了开路电位正移;(2)阴极极化能有效抑制微生物附着,并且阴极氧还原反应是阴极极化抑制微生物附着的主要原因;(3)搅拌等能促进阴极反应、增大阴极极化电流密度的措施都会在一定程度上利于阴极极化对微生物附着的抑制作用。
Characterization methods of fluorescence microscope and scanning electron microscopy （SEM） and electrochemical measurements of open circuit potential and potentiostatic polarization were used to study the interaction between biofilm adhesion and the cathodic potential of electrode surface in the natural seawater. The results show that： The adhesion of microorganisms on the electrode surface can cause the ennoblement of open circuit potential; Cathodic polarization can inhibit biofilm adhesion significantly, and electrochemical biofilm inhibition is closely related to cathodic reactions; The strategies which can promote cathodic reactions and increase the polarized current density are in favor of inhibiting biofilm adhesion.
