An innovative method using data acquisition and MATLAB for the electrochemical oxidation of formalin and the conversion of the oxidized products into a sound signal

Abstract

Abstract Aim: Herein, the oxidation of chemical compounds as sound signals, prepared either by chemical, physical, mechanical, biological methods were reported. Objectives: To fabricate the synthesized material for example, nanoparticle, ceramic, electro catalyst as electrode, by mixing the synthesized material with a suitable binder or they may be mixed with a solvent to function as an electrolyte. In this case, 40 % formalin as electrolyte, platinum and calomel electrode as positive and negative electrodes respectively have been used to formulate an electrochemical cell. Methodology: This cell is connected with the sound card to process the sound signals and analyzed using Sig view software. The sound signals after noise deduction were further processed using MATLAB to get information about the signals. Results: For example, Frequency, Amplitude, etc. of those cells can be obtained. The FFT spectrum obtained by this method correlates well with the FTIR spectrum of formalin. Any Conductive chemical oxidation could be processed in this way and their chemical information could be digitized and saved in cloud.
