Abstract
Toxic liquids, especially halogenated aromatic hydrocarbons, are immobilized within a container by dispersing cryogenically comminuted polymer particles in a surface active state throughout the liquid. The polymer is injected into a container holding the toxic liquid as a slurry of particles in a cryogenic refrigerant. Use of a heat, shear or radiation degradable polymer as the immobilizing agent allows the solidified liquid to be returned to a fluid state for later disposal by incineration.
