| Abstract: | Objective:To develop a simple and quick analytical method for determination of the picric acid in water.Methods:Trace picric acid in water was determined directly by capillary gas chromatography with automatic headspace sampler.Results:This method exhibited excellent relativity(r=0.9997)and good analytic precision(RSD<3.0%).The samples’ average recovery rates were in the range of 96.7%～99.5%.The detection limit(LOD)of the method was 0.004 μg/L,and the limit of quantification(LOQ)was 0.01 μg/L.Conclusion:This method was convenient,fast,sensitive and practical.It can be applied to the quick analysis for picric acid in water. |
