Abstract:

A high-performance liquid chromatography method with methyl acetoacetate derivatization via the Hantzsch reaction was developed for the analysis of formaldehyde (HCHO) in several water samples. Under optimized conditions, HCHO was detected within 4 min and was not affected by excessive derivatization reagents. The calibration curve constructed from the peak height of HCHO was linear, with a correlation coefficient of 0.9998. The relative standard deviation of the peak height from ten replicates was 0.29%. The detection and quantitative limits were 0.96 µg/L and 3.16 µg/L, respectively. A recovery test of HCHO was performed to compare the developed method with the official analysis method (DNPH method). The developed method was used to determine the HCHO levels in several water samples (tap water, river water, and waste water).
