    The chromotropic acid method for formaldehyde detection can be improved by using acetylacetone. Combining both methods enhances formaldehyde detection in various products.

    Area of Science:

    • Analytical Chemistry
    • Environmental Science

    Background:

    • The chromotropic acid method is a standard technique for formaldehyde determination.
    • This method can be hindered by masking discolouration, limiting its reliability.

    Purpose of the Study:

    • To evaluate acetylacetone as a complementary reagent for formaldehyde determination.
    • To improve the accuracy and reliability of formaldehyde analysis in diverse products.

    Main Methods:

    • Comparative analysis of the chromotropic acid method and the acetylacetone method.
    • Application of both methods to various product samples.
    • Evaluation of combined method performance for formaldehyde detection.

    Main Results:

    • The acetylacetone method serves as a viable alternative when the chromotropic acid method is compromised by discolouration.

  • Combining both analytical methods significantly broadens the scope of formaldehyde detection.
  • Formaldehyde was successfully traced in a wide range of products using the complementary approach.

    • Conclusions:

    • The acetylacetone method effectively complements the chromotropic acid method for formaldehyde analysis.
    • A combined approach using both reagents enhances the robustness of formaldehyde determination.
    • This strategy improves the ability to detect formaldehyde across various matrices.
