The provisions contained in the underlined standard constitute the main points of this standard through reference in this standard. When this standard is revised, the versions shown are valid. All standards will be reviewed: All parties using this standard should explore the possibility of using the latest versions of the following standards. GB/T6_9-1988 Sampling and Acceptance Rules for Chemical Reagents [15/T9721-19 Chemical Reagents Absorption Spectrophotometry (UV and UV-Visible Part)] 3 Method Summary
Weigh a certain amount of test sample, dissolve it with a specified solvent and prepare a drop of solution with a certain concentration, use a spectrophotometer to measure the concentration of the solution in a specified range, and calculate the absorbance coefficient of the reagent. The absorbance coefficient of the color former quantitatively reflects the degree of colored impurities in the reagent. · Reagents
Mononitrogen-containing alkane: pure,
Hazard: dangerous if inhaled, use with appropriate ventilation. Harmful if swallowed. 5 Instruments and equipment
5.1 Spectrophotometer: The sensitivity shall comply with the provisions of GB/T972, 5.2: Analytical balance: The sensitivity is 0.mg
5.3 Volumetric bottle: The concentration is 10 1nL.
6 Sample
Details according to GB/T619:
7 Steps
Weigh 1.0g sample (0.0022g) on ​​the analytical scale. Pour 10ml into a volumetric flask. Add difluoromethane and stir gently to dissolve the sample completely. Use monoxide to dilute the carbon rod to the scale and measure the sample. Use 1m sodium bicarbonate absorption cell on the spectrophotometer to measure the methane ignition rate. Compared with the solution, at the detection wavelength of 420nm, measure the absorbance of the sample.

Note: Individual colorants can be obtained at any time, in any area, or without any control. 8 Analysis results
The colorant absorption coefficient (e) is calculated according to the following formula: In the formula; Absorbance Coefficient, sensor trichloromethane micro-unit iridium degree and unit optical path length, at the specified wavelength (4211m> absorbance m:mL/(g-cm)
sample quotient's account luminosity;
sample whole law -B/mL
- avoid the optical path length of the sample tumor fluid. 9 allowable error
the difference between the results of two effective parallel measurements shall not be greater than (,r3nmL/-cm), take the previous error The sample arithmetic value is the result of the test.
Test report
The test report should include the following contents:
2. Sample name, batch date, manufacturer,
b. Test instruments and equipment;
c. All test data and results;
