Microfluidic chips are new devices that can manipulate liquids at the micrometer level, and terahertz (㎔) time-domain spectroscopy has good applicability in biochemical detection. The combination of these two technologies can shorten the distance between sample and ㎔ wave, reduce ㎔ wave absorption by water, and more effectively analyze the kinetics of biochemical reactions in aqueous solutions. This study investigates the effects of different external magnetic field intensities on the ㎔ transmission characteristics of deionized water, CuSO₄, CuCl₂, (CH₃COO)₂Cu, Na₂SO₄, NaCl, and CH₃COONa; the ㎔ spectral intensity of the sample solutions decrease with increasing intensity of the applied magnetic field. Analysis shows that the magnetic field leads to a change in the dipole moment of water molecules in water and electrolyte solutions, which enhances not only the hydrogen-bond networking ability of water but also the hydration around ions in electrolyte solutions, increasing the number of hydrogen bonds. Increasing the intensity of this magnetic field further promotes the hydrogen-bond association between water molecules, weakening the ㎔ transmission intensity of the solution.
