Effect of the strong magnetic field on copper adsorption processes on activated carbon

Vol. 8, no. 2

In the presented studies an influence of the strong static magnetic field on the process of copper adsorption on activated carbon was analysed. The magnetic field was generated by the annular neodymium magnets, placed at the bottom of the glass reactors, with the magnetic induction value at the surface equal 0.517 T. Additionally, during the study an effect of temperature on the adsorption process efficiency and its susceptibility to the external magnetic field was also investigated. As a result of the study, it was found that using a magnetic modification can increase the efficiency of the adsorption process up to 80%. However, such a strong influence of the external magnetic field was observed only in the case of relatively low initial and equilibrium concentration of the adsorbate. With the increase of the equilibrium concentration, stimulating nature of the magnetic field weakened significantly until finally at an equilibrium concentration about 80 mg/dm3, it was almost negligible. In addition, it was also found that the magnetic field modifications were much more efficient if the adsorption processes were conducted at the higher temperature.
