Electrolysis results in a comparison of metformin using aluminum, zinc, and iron (as the anode) as well as used carbon (as the cathode)
2020
Metformin is an antidiabetic drug that can be obtained easily in pharmacies/on the market, because it is traded freely, so people can easily buy and consume it. Ferrous metal, aluminum metal, and zinc metals are metal quite easy to find and are often used by the public. Metformin and Ferrous metal, aluminum metal and zinc metals are metal are quite familiar in the community. This research aims to deconcentrate metformin which can be obtained easily in pharmacies / on the market by electrolysis method, using ferrous metal, aluminum metal, and zinc metals are as an anode and carbon as the cathode. Electrolysis of metformin has been carried out using ferrous metal, aluminum metal, and zinc metal as an anode. The success of the electrolysis process was seen with a decrease in the sample COD index. In the case without the addition of electrolytes using ferrous metals, the COD index of the sample reduction was very low (9-17%). This research aims to increase the success of the electrolysis process, by adding various kinds of electrolytes, such as acetic acid (weak electrolytes), hydrochloric acid (strong electrolytes), sodium chloride and Fenton reagents. The addition of electrolytes can increase electrolysis yield significantly. The interaction between metformin during electrolysis is traced to the possibility of changes in the chromophore group (with UV-Visible spectra) and the functional group (with FTIR spectra) of the sample. From the research data obtained information that there is a decrease and shift in UV-Visible spectra and changes in functional groups after the electrolysis process occurs. The best electrolysis percentage is obtained, after adding NaCl solution and Fenton's reagent in the range of 50 -66%.
