“…The methods investigated included MLIS, AVLIS, and PSP. All three programs were successfully demonstrated in laboratory-scale, pre-prototype hardware tests in the United States (Tracy 1989).…”

“…The processes are specific to a single isotope per separation (Tracy and Terry 1985). The AIS selected AVLIS over PSP as the uranium enrichment method of the future, and the AIS pre-prototype PSP machine was transferred to Oak Ridge for use in production of stable isotopes (Tracy 1989 (Bigelow 2005). AVLIS was further developed for enrichment of uranium and plutonium.…”

“…The plasma separation process (PSP) was based on the ion cyclotron resonance of a charged particle in a uniform magnetic field to separate isotopes. 2) Chemical exchange methods, in particular, were found to be adequate for the separation of many elements. Among chemical exchange methods, crown ether has been considered to have a potential ability for isotope separation.…”

Chromatographic fractionation of zinc isotopes was performed on the synthesized benzo-15-crown-5 resin as a column packing material at 323 K in the breakthrough manner for both a frontal and a rear bands. Zinc adsorption capacity was affected by anion chloride concentration and solvent dielectric constant. The heavier zinc isotopes were found enriched to the solution phase and the lighter zinc isotope was concentrated on the resin phase. The frontal maximum enrichment ratio for isotopic pair of 68 Zn/ 64 Zn was 1.0081. The isotope separation coefficients for isotopic pair of 68 Zn/ 64 Zn for frontal and rear band, were 5:3 Â 10 À4 , 4:5 Â 10 À4 , respectively.

Adsorptive separation of Gd3+ ions was evaluated using DOWEX-50×8 ion exchange resin. It has shown a maximum adsorption capacity of 228.50 mg/g at optimum pH 5 and room temperature. Separation of Gd isotopes was investigated using packed bed columns of the resin in displacement chromatographic techniques where 1,2-cyclohexanedinitrilotetraacetic acid was used as displacer in the mobile phase. Isotopic analysis data by using MC‒ICP‒MS confirmed that the front end of the Gd adsorption band exhibited enrichment of the heavier isotope (160Gd), while the lighter isotopes (157Gd and 155Gd) were concentrated at the rear end of the stationary phase.
