Abstract
An HPLC procedure was developed for the determination of formaldehyde in milk. The analytical procedure consisted of the two-phase derivatisation reaction with 2,4-dinitrophenylhydrazine (2,4-DNPH) and elution of formaldehyde-2,4-dinitrophenylhydrazone (DNPF) from Lichrosorb RP8 column with acetonitrile-water (2:3) as mobile phase.
