UV-vis spectrophotometric determination of trinitrotoluene (TNT) with trioctylmethylammonium chloride as ion pair assisted and disperser agent after dispersive liquid-liquid microextraction

- Simple detection of trinitrotoluene with micro-volume UV-vis spectrophotometry.
- The method was applied to determination of trinitrotoluene in soil and water samples.
- Trioctylmethylammonium chloride (Aliquat 336) was used as disperser agent and anion carrier simultaneously.
- Detection limit is better than other method based on spectrophotometric detection.
