Finally. 5 Electromagnetic Separation ** This method uses the principle of the Mass Spectrograph Dempster ** For example, the beam of ions of the isotopes of neon Ne20, Ne21, Ne22 as obtained in the mass spectrograph, is then passed between the poles of a magnet.
semimetal just behind the coil. liquids at room temperature. These points are connected by two curves. Preliminary tests showed the potential usefulness of tertiary amines for recovering and purifying phosphoric acid from the highly contaminated wet-process acid produced in the fertilizer industry. Final report, November 1992--September 1994, CHEMICAL TECHNOLOGY DIVISION, CHEMICAL DEVELOPMENT SECTION C, PROGRESS REPORT ON SEPARATIONS CHEMISTRY AND SEPARATIONS PROGRESS RESEARCH FOR JANUARY-JUNE 1963, Effect of moisture-separator-drain routing on OTSG secondary-system chemistry.
