Development of a field method for ammonium picrate/picric acid in soil and water
- Army Cold Regions Research and Engineering Lab., Hanover, NH (United States)
Methods for the detection and quantification of ammonium picrate and picric acid in soil and water were developed. Picrate ions were extracted from water directly or from acetone extracts of soil by acidic, ion-exchange materials. Elution from the ion-exchangers was accomplished by converting the retained picrate to picric acid using strong aqueous acid/organic solvent mixtures. The resulting colorless solution was then converted back to a colored picrate solution by dilution with water. Quantification and correction for background interferences was based on spectrophotometric measurements. A chemical confirmation of picrate is possible for the water method. Method Detection Limits (MDLS) are 1.3 ppm for soil and 3.6 ppb for water. Both methods can be implemented under field conditions.
