This is to investigate the synthesis and improvement of metal-organic UiO-66 with research doping of manganese and cobalt elements and to analyze its performance in absorption and measurement of tetracycline. Doped structures of Mn-UiO-66 and Co-UiO-66 using X-ray jump analysis, X-ray fluorescence measurement, infrared Fourier transform experiment, scanning electron microscope, porosimetry analysis, X-ray energy diffraction investigation, with elemental mapping. Thermal weighing analysis, inductively coupled plasma mass analysis and visible-ultraviolet analysis were investigated to determine the structural characteristics and absorption efficiency of tetracycline. Then, electrodes composed of metal-organic electromagnetic electrodes UiO-666 with manganese and cobalt and multi-walled carbon nanotubes (MWCNTs) on glassy carbon electrode (GCE) were prepared and the production and dechemical deposition of gold nanoparticles was done by cyclic voltammetry (CV) method. The electrochemical characteristics, electrocatalytic behavior and tetracycline oxidation process were analyzed by the cyclic voltammetry (CV) method by composite electrodes, on metal-organic bases doped with manganese and cobalt. Finally, tetracycline was detected by differential pulse voltammetry (DVP) by Mn-UiO-66/MWCNTs/AuNPs/GCE and Co-UiO-66/MWCNTs/AuNPs/GCE composite electrodes and its results were eva‎luated. The results show a significant improvement in the structural and functional characteristics of organometallics, which increases the efficiency in the absorption and detection process of tetracycline. By introducing new methods of synthesis, doping and comprehensive material analysis, this research helps to improve the performance of composite electrodes and develop sensitive and accurate biosensors. After all, these methods can be used as a new target in improving the properties of chemical adsorbents and developing electrochemical sensors.
