Study of the treated and magnetically modified bentonite as possible
Bentonite with its unique structural properties is a valuable material for environmental application. Its sorption propertiesare usually improved by the different ways of modification. In this work, the special sedimentation method was used for the treatment ofthe natural bentonite to obtain monomineral fraction of montmorillonite. The modification by iron oxide particles was used with the aimto prepare the magnetic sorbent with enhanced sorption properties of treated bentonite. The removal of nickel from aqueous solutions bythe natural, treated and magnetically modified bentonite was studied in batch adsorption-equilibrium experiments. The experimentaldata were fitted with Langmuir and Freundlich isotherms. The sorption capacities of the natural, treated and modified bentonite werecompared.
