Isotope separation by parametric pumping and heatless adsorption. Final report

Separation of boron isotopes by p a r a m e t r i c pumping was accomplished using a boron trifluoride-dimethyl sulfoxide s y s t e m .Hydrogen isotopes w e r e separated continuously in an H -D _ gas mixture using palladium by a cyclic p r o c e s s called £t f* heatless adsorption.Enzyme separation was also demonstrated to o c c u r in a pH p a r a m e t r i c pump.In each c a s e the separations w e r e l e s s than predicted by simple equilibrium theory f o r the p r o c e s s e s ; however the theory does allow evaluation °f potential isotope separations based on single-stage separation f a c t o r s .This work has been presented in four Annual P r o g r e s s R e p o r t s and is s u mmarized in this Final Report.
