This invention achieves simultaneous, accurate, rapid, and stable detection of multifunctional components in Acer truncatum leaves.

This invention discloses a rapid spectroscopic detection method for the purity and impurities of industrial hydrochloric acid, belonging to the field of chemical analysis and detection technology. The method uses a deuterium-tungsten composite light source and a miniature fiber optic spectrometer to collect ultraviolet absorption band spectral data and visible light absorption band spectral data. After preprocessing and characteristic wavelength screening, a dual-objective partial least squares correction model is established to achieve simultaneous prediction of purity and impurities. Mutual interference is eliminated through impurity interference compensation and purity feedback correction mechanisms. Combined with spectral quality evaluation, the reliability of the results is ensured. This invention achieves a single detection time of less than 1 minute, a purity accuracy of ±0.5%, and an iron impurity detection limit of 5 ppm.
