    A new method for determination of formaldehyde is described. Formaldehyde is continuously collected in a cylindrical wet effluent diffusion denuder into a thin film of distilled-deionized water used as an absorption liquid. Collected formaldehyde is on-line detected in the denuder efluent by means of flow injection method based on a chemiluminescence reaction in which formaldehyde reacts with gallic acid and hydrogen peroxide in a strong alkaline solution

    Je popsána nová metoda pro stanovení formaldehydu ve vzduchu. Formaldehyd je kontinuálně zachytáván v cylindrickém difúsním denuderu se stékajícím filmem kapaliny do tenkého filmu deionizované vody, která je použita jako absorpční kapalina. Zachycený formaldehyd je on-line detegován v koncentrátu z denuderu pomocí FIA metody založené na chemiluminiscenční reakci, kdy formaldehyd v alkalickém prostředí reaguje s kyselinou galovou a H2O2
