Determination of 2-Chlorovinylarsonic Acid in Environmental Waters by Ion Chromatography

Abstract

Lewisite, through its hydrolysate 2-chlorovinylarsonous acid, is thought to oxidize gradually in seawater, freshwater, and soil to form 2- chlorovinylarsonic acid (CVAOA). Like lewisite, CVAOA is also a potential vesicant. The high-performance liquid chromatography method is described here to directly detect and analyze CVAOOA in seawater and surface water. Separating CVAOA from the aqueous matrix is carried out using both conventional (ion exchange) and ion-pair reverse phase ion chromotography. Using eluent suppression conductivity and ultraviolet as dual modes of detection, the detection limit is 10 ng. Keywords: Lewisite analysis, Chlorovinylarsonous acid, Liquid chromotography, Seawater analysis, Environmental water analysis.
