ABSTRACT:
Krypton and/or xenon are extracted from a krypton-xenon concentrate by means of distillation, for example, a krypton-xenon concentrate obtained from a low-temperature air separation unit. To remove fluorine- and/or chlorine-containing contaminants, especially fluorocarbons, CF.sub.4 and/or SF.sub.6, the krypton-xenon concentrate, a krypton stream and/or a xenon stream are purified in a solid sorbent that contains phyllosilicates.
