A method using(2,4-Dinitrophenylhydrazine, DNPH) as pre-column labeling reagent followed by ul-tra performance liquid chromatography (UPLC) with Photo-Diode Array detector (PDA) has been developed for the determination of three aldehydes (glyoxal, formaldehyde and glutaraldehyde) in textile samples. Test process in-cludes:reagent preparation, sample pretreatment, derivatization, optimization of chromatographic conditions and eval-uation of analyzing method. The chromatographic conditions of the method are that: detection wavelength is 360 nm, column temperature is 30 ℃, injection volume is 10 μL, elution flow rate of is 0.8 mL/min. Under these conditions, the quantification limits for the desired compounds ranging from 20 to 28 μg/L are obtained, and the recoveries are higher than 97.8%. The proposed method is successfully applied to the determination of the target compounds in textiles with a higher sensitivity.
