    1. From the specific optical density
    2. Development of coloration and measurement of optical density
    3. E corrected optical density, determined as indicated in 5.2,
    4. Determine the optical density of the blank test solution (D) by comparison with the reference solution (C), and the optical density of the sample solution (B) by comparison with the reference solution (A), in the spectrophotometer at 440 nm using 1 cm glass cells. Subtract the optical density of the blank test solution from that of the sample solution (= corrected optical density).
