Abstract:

After reacted with 2,4- dinitrophenylhydrazine under acidic condition and yielded hydrazone derivatives, seven aldehydes were determined by HPLC with acid diode array detector. The method of determination of seven kinds of aldehydes in the textile by HPLC at one time has been developed . The results show seven kinds of hydrazone are favorably separated. In the range of 0.15～7.5 ug/mL, there are good linear relationships with correlation coefficient beyond 0.9994, the average recovery of each aldehyde is in the range of 85.4 %～97.8 %, the variable range of relative standard deviation is 0.2 %～7.6 %, the detection limit which is less than the limitation requirement of Chinese National Standard is in the range of 2.2～4.5 mg/kg . This method can be applied to detect aldehydes in the textile.

Key words: formaldehyde, glyoxal, glutaraldehyde, high performance liquid chromatography, textile
