Abstract

The use of large volume injections has been studied for the verification of intact organophosphorus chemical warfare agents in water samples. As the use of ethyl acetate caused severe detection problems new potential solvents were evaluated. With the developed procedure, the nerve agents sarin, tabun, soman, DFP and VX can be determined in freshly prepared water samples at ppt levels. Except for the nerve agent tabun all other agents added to the water samples were still present after 8 days at 20-60% levels, if the pH of the water sample is adjusted to ca. 5 shortly after sampling and adjusted to pH 7 for analysis.

摘要

已对使用大量进样法验证水样中完整的有机磷化学战剂进行了研究。由于使用乙酸乙酯会导致严重的检测问题，因此对新的潜在溶剂进行了评估。采用所开发的方法，可以在新制备的水样中测定ppt水平的神经性毒剂沙林、塔崩、梭曼、二异丙基氟磷酸酯（DFP）和维埃克斯（VX）。如果在采样后不久将水样的pH值调节至约5，并在分析前将其调节至pH 7，则除神经性毒剂塔崩外，添加到水样中的所有其他毒剂在20-60%的水平下8天后仍会存在。
