Self-calibration measurement method and system for concentration spectrum of boric acid solution by using Raman spectrum

The embodiment of the invention provides a self-calibration measurement method for the concentration spectrum of a boric acid solution by using a Raman spectrum. The method comprises the following steps: a Raman spectrum of a solution containing a Raman characteristic peak of a calibration object under a specific concentration is obtained as a standard spectrum, the calibration object is arranged in a light path of a Raman spectrum system, and the calibration object is not located in the solution to be detected; obtaining an original Raman measurement spectrum of the solution to be detected; based on the standard spectrum, obtaining Raman scattering light intensity within a preset range around the characteristic peak position of the calibration object; calibrating the original Raman measurement spectrum based on the Raman scattering light intensity to obtain a Raman calibration spectrum; and obtaining the concentration of the to-be-detected solution based on the Raman calibration spectrum. Based on the method
