| Abstract: | Determination of sulphite in compound amino acid injection was done by colorimetry. In spectrophotography, basic fuchsin formaldehyde solution was used as chromogenic agent and detection wavelength was at 576nm. The calibration curve was linear in the range of 0.4~2 μg·mL~ -1 of sulfur dioxide. The correlation coefficient was 0.9923(n=5) and the average recovery was 99.9% (RSD=1.19%,n=9).The method is simple,rapid,accurate and suitable for the quality control of the producr. |
