Abstract |
Identification of alkyl methylphosphonic acids in aqueous samples is important for the monitoring compliance with Chemical Weapons Convention. In order to analyze the alkylmethylphosphonic acids in the complex matrices, it is essential to remove the interfering substance through a sample preparation process. In this study, we propose solid phase extraction of alkyl methylphosphonic acids using gold chips coated with poly(triethylammonium ethyloxymethacrylate) film prepared by surface initiated polymerization and the on-chip silylation of extracted alkyl methylphosphonic acids for Headspace GC-MS analysis. In this study, the proposed analytical method was optimized and verified through a series of experiments. The optimized method was successfully applied to OPCW proficiency test sample. |
