  • Process and installation for the decontamination of radioactive nitric effluents containing strontium and sodium
    Patent number: 5702608
    Abstract: The invention relates to a process and an installation for the decontamination of radioactive nitric effluents containing strontium and sodium. According to this process, contacting takes place in 1 of the aqueous effluent with an organic phase incorporating a crown ether such as DCH18C6 and a diluent such as CHCl.sub.3, in order to selectively extract the strontium with respect to the sodium, followed by the reextraction of the strontium in an aqueous solution in 3, followed by fixing in 5 on a cation exchange resin. This leads to a high strontium decontamination level with a very high concentration factor.
