Add 2.5ml of solution (14.3.2) to the scale with water, and add 1.1% water to the scale, and then ... 2 Monitor and test according to the requirements of G15/T7223 and the dust-proof part, stop the fire at 218.3° with air, use water to check the absorbance of the test solution, and draw three plates of chemical fast-acting liquid from the calibration curve. 14.5°C. Transfer 100ml of 0.2.00, 4.00, 3.00, 10.ccm. of standard iron ion solution (11.4.2) into a container and dilute the sample to the specified concentration using 11.1°C. In the absorption spectrum at a wavelength of 23°, water is used to adjust the zero point, and the absorbance is measured. The absorbance is taken as the vertical coordinate with the concentration of trioxide as the vertical coordinate and the absorbance of zero concentration as the vertical coordinate. The super-variable curve is drawn. 15. Summary of the analysis results
According to formula (2), the mass percentage of trioxide is screened, Fo.
