Embodiment 1

[0039] A kind of method of rapid combined quantitative determination of propionic acid and ammonium propionate of the present embodiment, described method is used for measuring the content of propionic acid and ammonium propionate in antifungal agent, described method comprises the following steps:

[0040] (1) Preparation of reagent materials: the concentration is C NaOH Sodium hydroxide standard solution, phenolphthalein indicator solution and formaldehyde solution;

[0041] (2) Sample preparation: mix the sample of antifungal agent to be tested and set aside;

[0042] (3) Sample treatment: Accurately weigh a sample of the antifungal agent to be tested with a mass of m, place it in a 250mL Erlenmeyer flask, add 100mL of distilled water, then add 2 to 4 drops of phenolphthalein indicator, shake well and obtain the sample to be tested sample liquid;

[0043] (4) measure: the test sample liquid that step (3) is obtained is titrated with described sodium hydroxide standard sol...
