Evaluation of an XAD-4 Resin Extraction Method for Dimethylmethylphosphonate and Trimethylphosphate in Water.

摘要

The Army is concerned with the removal of dimethylmethylphosphonate (DMMP) and trimethylphosphate (TMP) from water by treatment with activated carbon. In order to effectively evaluate the removal of these contaminants from water, a reliable method is required to measure the concentration of these contaminants present in the water before and after treatment. Determination of these compounds in previous contract work (DAAKll-78C-0132) using the EPA priority pollutant protocol gave low and erratic recoveries. The purpose of this study is to test and evaluate an analytical method, provided by the Dept. of the Army, for DMMP and TMP in aqueous solution. This method differs from the EPA priority pollutant protocol in that a macroreticular resin, XAD-4, will be used to extract DMMP and TMP from aqueous solution. (jg).
