METHOD OF SEPARATELY DETERMINING α-, β-LEWISITES, THEIR OXIDES, AND CHLOROVINYLARSONIC ACIDS WHEN PRESENT IN COMMON IN SOIL Russian patent published in 2003 - IPC

FIELD: analytical methods. SUBSTANCE: method can be used when effecting environmental monitoring on chemical weapons-destruction installations. Separation of α- and β-lewisites, α- and β-lewisite oxides, and chlorovinylarsonic acids is performed in the stage when soil samples are prepared involving liquid extraction methods, and determination of amount of substance in extract is fulfilled from amount of acetylene evolving upon treatment with 30% sodium hydroxide aqueous solution. EFFECT: enabled integrated analysis of α- and β-lewisite and their degradation process products in soil. 6 cl, 3 tbl
