| Abstract: |
| Association reaction between picric acid and crystal violet was studied. A flotation-spec-trophotometric method based on the reaction has been developed for the determination of trace picric acid in water. It was found that the sensitivity and selectivity of this method were fairly good. |
| Key words: picric acid flotation spectrophotometry water sample |
