| Abstract: | A method was established for determining Picric Acid in water by GC-ECD.Picric acid in the water was derivatized with sodium hypochlorite in 40 min,and then extracted with n-Hexane in 5 min.Good linearity was obtained in range from 5.00 μg/L to 100 μg/L,detection limits 0.2 μg/L,relative standard derivation of blank duplicates 2.2%,spiked recoveries between 89.6% and 95.0%. |
