  • 摘要:Three types of electrodes were obtained and characterized in order to use for detection of some electrochemical oxidable organics conventionally considered responsabile in COD parameter evaluation: electrodes based on undoped and Co-doped lead dioxide, electrodeposited from slight acidic solutions on stainless steel support; electrodes based on copper/copper oxides obtained in situ in alkaline medium by potential cycling between the selected potential values or by polarization to a fixed potential value. The electrochemical and un-electrochemical characterization of the obtained electrode materials was studied. Detection experiments and calibration tests provided informations regarding: amperometric detection type, detection potential value, amperometric oxidability level (AOL), electrode sensitivity, concentration ranges, stability, reproducibility of signal, detection limits, and lifetime.
