Abstract

A method of and apparatus for the purification of a liquid contaminated with radioactive substances, wherein the liquid is infed to an evaporator in or with which there is connected a column having a multiplicity of superposed plates or floors. The vapor generated in the evaporator is guided through a washing or scrubbing liquid uniformly distributed at the floors and flowing in crosswise counterflow with regard to the vapor. The washing liquid at the floors is deflected a number of times in such a manner that the washing liquid itself and together with the droplets entrained by the vapor is uniformly admixed and the washing liquid subjected to a constant intake of the radioactive substance.
