description The invention discloses an ultraviolet spectrum detection method and device for monitoring trace H2S in blast furnace flue gas. The device comprises a light source (1), a spectroscope (9), a sample pool (2), a reference pool (3), a detector (4), an arithmetic unit (5) and a reflector (10), a spectral measurement device further comprises a component elimination device (6), a pump P1 and a valve V1V4. The incident light emitted by the light source (1) is transmitted light and reflected light with the same light intensity after passing through the spectroscope (9), wherein transmitted light is incident to the mixed component in the sample pool(2); and the reflected light enters the reference pool(3) without the mixed component; the detector (4) detects the light intensity of the transmitted light and the reflected light; and the arithmetic unit (5) is used for carrying out differential treatment on the transmitted light intensity obtained by the detector (4) to obtain the component concentration.
