What is Changes of the Adsorption Parameters Under the Influence of Static Magnetic Field about?

During the study, the influence of the external magnetic field on the adsorption of copper, nickel and cadmium were analysed. For that purpose, two different types of charcoals were used, paramagnetic and ferromagnetic. Obtained results showed clear changes in the effectiveness of adsorption processes under the influence of the strong magnetic field, but only for the ferromagnetic activated carbon. The stimulating nature of the modification on the copper removal processes has been proved while for nickel adsorption systems, an inhibiting effect of the same kind of field was demonstrated. For cadmium removal, there were no statistically significant changes in the processes before and after magnetic modifications. Besides that, additional parameters were studied like kinetic and thermodynamic analyses of the systems and it also proved the important influence of the static magnetic field, such as increase of the initial adsorption rate or changes in entropy, and the average Dubinin–Radushkevich energy of the process.
