Sorption of asymmetric dimethylhydrazine vapor by peaty soil was inves
tigated. Sorption isotherms were measured by a dynamic method at 32-50
-degrees-C. The type of sorption of the compound with the soil surface
was determined from the calculated enthalpies of sorption. The abilit
y of asymmetric dimethylhydrazine to migrate from the soil to other ob
jects of the environment and to be removed from the soil by thermosorp
tion was evaluated.
