Assessing the Salt Constituents Characteristics in Aqueous Solutions Using Terahertz Waves

This paper proposes a viable technique for the precise quantification of various amounts of salts added to distilled water using terahertz (THz) frequency. For this purpose, Fourier transform Infrared Spectroscopy (FTIR) system was employed to observe the absorption spectra and characteristics of salts solutions with varying level of salts. In this study, distinct absorption spectra peaks were achieved for different concentrations of salt solutions at certain sensitive THz region. The height of absorption peaks showed a strong correlation with the amount of salt added to the solution reflecting meaningful information about the presence of salts molecules added in distilled water. Through the outcomes of our study, we propose a method through which different minerals and potentially harmful contaminants can be found in water
