| Abstract: | The method for determination of picric acid in water was optimized.Picric acid was extracted by low toxicity hexane replacing benzene which was highly toxic and carcinogenic to humans,determinated by gas chromatograpy.The results showed that the method’s detection limit was 0.44μg/L,standard deviation was 0.146%(n=7) and recovery rate was 90.7% to 116.8%.It was experimentally proved that this method met the requirment of GB 3838-2002 and was environmentally friendly compared with recommendatory method. |
