WATER QUALITY ANALYZER AND WATER QUALITY ANALYSIS METHOD

摘要

According to the present invention, a correction calculation unit 102 corrects absorbance by performing calculation by using a correction equation on the basis of the absorbance calculated by an absorbance calculation unit 101 at each wavelength. A turbidity component detection processing unit 103 provides a turbidity standard solution to an oxidation reaction unit, irradiates the turbidity standard solution after oxidation reaction with measurement light from a light source 51, and causes a detector 52 to detect the intensities at a plurality of wavelengths of the measurement light that has passed through the turbidity standard solution. A correction coefficient update processing unit 104 calculates the absorbance at each wavelength by means of the absorbance calculation unit 101 on the basis of the intensities, which are detected by the turbidity component detection processing unit 103, at the plurality of wavelengths, and updates update coefficients stored in the storage unit 200 on the basis of the absorbance calculated at each wavelength.
