Ultraviolet spectrophotometer is an effective method to study the composition, structure and interaction of substances based on the absorption spectrum of substances. The UV spectrophotometer can arbitrarily select light of different wavelengths in the UV-visible region. The absorption spectrum of a substance is the result that the molecules and atoms in the substance absorb the light energy of certain specific wavelengths in the incident light, and the molecular vibrational energy level transition and the electronic energy level transition occur accordingly. Since various substances have their own different molecules, atoms and different molecular spatial structures, their absorption of light energy will not be the same. Therefore, each substance has its own unique and fixed absorption spectrum curve, which can be Determine the absorbance of certain characteristic wavelengths on the spectrum or determine the content of the substance.
