      liquid chromatography].
PG  - 562-4
AB  - A high performance liquid chromatographic (HPLC) method was developed for the 
      separation of formaldehyde and phenol from the other components of resol resins. 
      The sample was dissolved in methanol and treated with 2,4-dinitrophenylhydrazine 
      in order that formaldehyde was derivatized to form 2,4-dinitrophenylhydrazone 
      with high UV absorbance. The separation was carried out on a Waters Symmetry C18 
      column (5 microm, 4.6 mm x 250 mm) with methanol-water (43:57, v/v) as the mobile 
      phase at a flow rate of 0.8 mL/min. The detection wavelength was 270 nm for 
      phenol and 360 nm for the derivative of formaldehyde. The results showed that 
      derivatization had no effect on the determination of phenol. The relative 
      standard deviations (RSDs) of the contents of phenol and formaldehyde were below 
      5%, the limits of detection (LODs) were below 1 microg/L, and the recoveries were 
      between 96% and 105%. With this method, formaldehyde and phenol in the resol 
      resins can be determined by only one injection. As a result, this method would 
      meet effective control for quality of this kind of resol resins.
