In this work, a new method for preparing samples with 2-chlorovinyl dichlorosine is optimized: its main difference from the prototype consists in the application of the combined adsorption–extraction process instead of the method of absorption by bubbling. The optimization includes the selection of an adsorbent and the sampling conditions (concentration of the analyzed substance vapors, composition of the eluent, and rate of the vapor-air flow). The positive effect of the low specific surface of the adsorbent on the degree of the extraction of the adsorbate is established. The optimal volume ratio of ethanol and hydrochloric acid is proposed, which allows us to almost completely extract the reagent.
