Chlorovinylannes (Lewisites) were produced and handled during WW I and WW II as chemical warfare agents. Residues of these
cwa and their metabolites are still present today and continue to contaminate soil and water.
A gas Chromatographic method for the detection and determination of chlorovinylarsines (Lewisites) and their metabolites is
shown. Lewisite II and Lewisite III, but not Lewisite I and the metabolites of Lewisite I and Lewisite II can be detected
and determined using GC/ECD. After derivatization with thiols, the sum of Lewisite I or Lewisite II and their metabolites
are detected. With the proper selection of the thiol, matrix interferences can be eliminated because of the different retention
times of the derivatives. 相似文献

Ethylarsine dichloride was used during WW I as a chemical warfare agent. Residues of this chemical warfare agent and its metabolites
are still present today and continue to contaminate soil and water.
A gas Chromatographic method for the detection and determination of ethylarsine dichloride is shown. Six dithiols were tested
as possible derivatization reagents for ethylarsine dichloride. With selection of the dithiol, matrix interferences can be
eliminated because of the different retention times of the derivatives. 相似文献
