Abstract |
The detection of chemical Warfare Agents (CWA) and the related chemicals is important for CWC compliance monitoring. Nerve agent, a kind of CWAs, is hydrolyzed to alkyl phosphonic acid in water and soil. Conventional identification methods such as GC-MS, LC-MS and NMR for alkylphosphonic acids require several steps of sample preparation. In this study, anion exchange film was prepared by surface-initiated polymerization on gold plates using trimethyl ammonium functionalized methacralate to selectively extract alkylphosphonic acids from aqueous samples and analyzed by FT-IR spectroscopy. The prepared plates were immersed in an aqueous samples for 10 minutes and then washed with deionized water for extraction of alkylphosphonic acids. The washed plates were briefly dried in a stream of nitrogen gas prior to FT-IR analysis. FT-IR was able to successfully analyze concentration samples at ppm levels. |
