摘要：

The quantitative analysis of hydrogen peroxide in water solution (25% similar to 30%) is studied on short wavelength,near-infrared spectrometers (Grating, CCD Detector) and long wavelength near-infrared spectrometers (FT, InGaAs Detector) respectively. It was found that analytical accuracy obtained from SW-NIR ( short wavelength near-infrared) spectrometer with long optical path is significantly better than LW-NIR (long wavelength near-infrared) with short optical path, because long pathlength can compensate the affect of bubble (come from degradation of hydrogen peroxide) on spectral measurement precision at some extent. The root mean square error cross-validation (RMSECV) and root mean square error of cross validation and prediction (RMSEP) is 0.06 and 0.05 respectively for SW-NIR model, 0.10 and 0.09 for LW-NIR model. The above results show the feasibility of SW-NIR technology for the determination of the concentration of hydrogen peroxide (25% similar to 30%) in water solution.
