This method is based on the reaction of Fluoral-P (4-amine-3-pentene-2-one) with formaldehyde, leading to the formation of 3,5-diacetyl-1,4-dihydrolutidine (DDL), which fluoresces at λex = 410 nm and λem = 510 nm. The analytical parameters were optimized by the response surface method using the Box–Behnken design. The proposed flow injection system allowed for the determination of up to 3.33 × 10−5 mol L−1 of formaldehyde with R.S.D. < 2.5% and a detection limit of 3.1 ng mL−1. The method was successfully applied to determine formaldehyde in alcoholic beverages, without requiring any sample pretreatment, and the results agreed with the reference at a 95% confidence level by paired t-test. In the optimized condition, the FIA system proved able to analyze up to 60 samples/h.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-01-14T16:45:33Z No. of bitstreams: 1 1-s2.0-S0039914007002779-main.pdf: 594749 bytes, checksum: 54e796a35cfe5e2e7a9b0a46a6884a0f (MD5)Made available in DSpace on 2014-01-14T16:45:33Z (GMT).
