Concentration of isotopes of potassium by the counter-current electromigration method.
A new electromigration method for the separation of isotopes is described. This method ba ed on the pririciple of setting up a flow of electrol yte tlu'ough a packed column in a direction counttlJ"current to the flow of the i otopic ions being separated and at a rate intermediate between the velocities of these ions. Under these conditions, the faster moving ions will make headway against t he ...
متن کاملNitrogen Isotope Separation by Ion Exchange Chromatography
Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...
متن کاملI. The separation of sodium from potassium in human blood serum by ion exchange chromatography.
The experiments to be described were undertaken to devise a simple and rapid technique for the separation of sodium from potassium in human blood serum in order to facilitate the simultaneous measurement of exchangeable sodium and potassium in man by the isotope dilution technique. This technique requires the intravenous administration of a known amount of radioactive sodium (Na24) and radioact...
متن کاملSeparation of Potassium Isotopes in Valonia and Nitella
The ratio of K(39) / K(41) appears to be lower in the sap of Valonia and Nitella than in the environment, indicating that the living cell can separate these isotopes to some extent. Experiments with a mixture of guaiacol and p-cresol suggest that a similar separation may occur here but further experiments are needed.
متن کاملSeparation of adrenaline, noradrenaline, and hydroxytyramine by ion exchange chromatography.
Methods for the separation of adrenaline, noradrenaline, hydroxytyramine, and dihydroxyphenylalanine (dopa) by employing starch columns (2, 3), paper chromatography (4-7), or countercurrent extraction (8) have limited usage either because of the length of time required for the fractionation or because of the small amounts of material that can be separated. A procedure is described below in whic...
