Abstract:
Speciation of Cu(II), Cd(II) and Ni(II) ions from aqueous solutions by means of the magnetic amino-functionalized polymer/bentonite composite based on methacrylates was investigated. The influence of contact time and initial concentration was monitored and the obtained data were analyzed by kinetic models, as well as the Langmuir and Freundlich adsorption isotherms. The composite was shown to be very efficient in the sorption of investigated ions, which can effectively be removed from aqueous solutions by applying the external magnetic field.
