Abstract

The invention discloses a method for analyzing volatile carbonyl compounds in water-based adhesive through direct deviation-high performance liquid chromatography. A water-based adhesive sample and a 2,4-dinitrophenylhydrazine acid solution are directly subjected to the derivatization reaction, and the content of the carbonyl compounds in the water-based adhesive is analyzed through the high performance liquid chromatography. A DIONEX Acclaim Explosives E2 column is adopted, water and acetonitrile are taken as a mobile phase for performing binary gradient elution, the flow rate is 1.2mL / min, the sample injection volume is 10 mu L, the detection wavelength is 365nm and the temperature of a chromatographic column is 35 DEG C. By adopting the method, the volatile carbonyl compounds in the water-based adhesive can be effectively analyzed, the method is fast, reliable, simple and practicable, the enrichment process of the volatile carbonyl compounds in the sample is achieved, the loss of detected substances during the pre-treatment process of the sample can be reduced, the detection limit is low and the accuracy is high.

Description

technical field

[0001] The invention relates to the detection of harmful components in water-based glue, in particular to a method for analyzing carbonyl compounds in water-based glue by direct derivation high-performance liquid chromatography. Background technique

[0002] The application of water-based adhesives has been developed into various fields of people's production and life, but the harmful volatile carbonyl compounds in water-based adhesives have a great impact on human health. At present, the detection of harmful substances in water-based adhesives mainly focuses on benzene and benzene series, phthalates and aldehydes. There are high performance liquid chromatography, gas chromatography and solvent extraction methods for the detection of volatile carbonyl compounds in water-based adhesives, and these three methods are mainly aimed at two carbonyl compounds, formaldehyde and acetaldehyde, in cigarette water-based adhesives. So far, no direct derivatization HPLC m...
