METHOD OF SOLID-PHASE CHEMISORPTION CONCENTRATION OF BETA- CHLOROVINYLDICHLOROARSINE FROM AQUEOUS SOLUTIONS FOR SUBSEQUENT ASSESSMENT AT MICROCONCENTRATION LEVEL Russian patent published in 2000 - IPC

Abstract RU 2146819 C1

FIELD: analytical methods. SUBSTANCE: invention relates to examination and analysis of materials by isolating them from complex matrices. Method can be applied in military and industrial indication systems when estimating propagation area of dangerous concentrations of injurious substances, at chemical weapons destruction enterprises, and also in environmental monitoring. Chemisorption concentration of lewisite is adsorbed on anion-exchange resin modified with 2,3-dimercaptopropanesufonic acid sodium salt and assessment of isolated lewisite is accomplished from amount of acetylene released when adsorbent is treated with aqueous alkali solution. EFFECT: increased lewisite isolation degree providing detectable concentrations of substance. 2 cl, 4 tbl
