Magnetic Field Effects on the Adsorption of Metal Ions onto the Chelate Resine

Abstract

An adsorption of metal ions on the Dowex chelate resin A-1 was examined by means of a batch and column methods in the presence of magnetic field. Metal ions used were Fe(III), Ni(II), Co(II), Cu(II) and Zn ions. Magnetic flux density was 0.12 T (batch metho d) and 0.2 T (column method). An amount, velocity and rate of adsorption were increased by the magnetic field effects. The velocity of adsorption increased by about 3-50% compared with their values in the absence of magnetic field by a batch method. Most efficient concentration of metal ion was about 0.1 mg/cm3, and that of flow rate was 30 cm3/min (Fe(III), Ni(II) and Cu(II) ions), 20 cm3/min (Co(II) ion), and 45 cm3/min (Zn ion) by a colum n method. The adsorption rate increased by about 1-11% compared with their values in the absence of magnetic field. Fe(III) ion was 1.0-6.5%, Ni(II) ion was 7-11%, Co(II) ion was 1.0-2.2%, Cuan was 0-2.0%, and Zn ion was 4.0-9.0%. The adsorption amount per unit mass of the resin increased by about 1-6% by both methods in the presence of the Magnetic field. It was assumed that the magnetic field effects was the cost down on the working operations.
