Abstract

In order to observe the spectroscopic characteristics of metallic ion in soil in terahertz region, terahertz time-domain spectroscopy (THz-TDS) was used to analyze the absorption coefficient and refractive index in the frequency range 0.2 ~1.6 THz at room temperature. In the present work, we designed several kinds of soil samples (i.e. different content copper sulphate and zinc sulphate in soil).The terahertz time-domain spectra of samples were measured. The experimental results indicate that the metallic ion in soil has many distinct characteristic spectra between 0.2 and 1.6THz. This study can not only assign the characteristic absorption of the sample, but also can provide the absorption frequencies in wider effective spectra range. The results show that the THz-TDS can be used to measure the metal residues in the soil.
