Abstract:
Objective To establish a method for determination of 13 kinds of aldehyde and ketone pollutants in indoor air by HPLC at one time. Methods The aldehyde and ketone compounds in the air react with 2 4-DNPH and form hydrazone derivatives then determined by HPLC with SPD detection at a flow of CH3CN∶H2O 70∶30 365 nm wavelength. Results 13 kinds of hydrazone were favorably separated the average recovery rates were 96%～101% the lowest detection limits were 0.002～0.02 mg/m3 the linearity range was 0.1～4.0 mg/m3. Conclusion This method can be used for quantitative analysis of 13 kinds of aldehyde or ketone pollutants in indoor air at one time.
