| titleOfInvention | Method for determining unsulfonated primary aromatic amine in amaranth |
| abstract | The invention relates to a method for measuring unsulfonated aromatic primary amine in amaranth, which is a colorimetric method, wherein a standard diazotization coupling solution and a sample diazotization coupling solution are respectively placed in a cuvette, the absorbances Aa and Ab of the standard diazotization coupling solution and the sample diazotization coupling solution are measured by a spectrophotometer at the wavelength of 510nm, and a blank solution is used as a reference solution. The method has the advantages of simple operation, strong specificity, high sensitivity and good repeatability. |
