- Abstract
Magnetic field (MF), among others, influences more intense decomposition of many compounds, increases adsorption on the surface of the phase separation, as well as accelerates oxidation and reduction reactions. Therefore, they are used in the research as an aid for filtration process, which is one of the most popular stopping and separating processes for different components in different reservoirs. Beds usually function as an adsorbent, thus both filtration and adsorption processes are often. One of the inorganic sorbents that is used to remove metals and anions present in water is Al2O3. As part of this work, we investigated the use of a constant external MF as an elementary additional process to improve the filtration efficiency on activated alumina. The purpose of the study was to compare the effectiveness of the removal of elements (Fe, Mn, Cd, Cr, Cu, Pb, Zn, and Ni) from model aqueous solutions during the process of filtration assisted and not assisted by an MF on activated alumina. In addition, the purpose of the work was also to determine the influence of MF on the removal of these elements, as well as their affinity to physical properties of the adsorbate under the influence of MF. As a result of the experiment, it was proved that the MF support of the filtration on activated alumina for the removal of selected elements is more effective than the filtration without MF. Studies have shown that removal of individual metals occurs according to the following series of affinity toward alumina in magnetized samples: Pb > Mn > Ni > Zn > Cu > Fe > Cd > Cr.
