Adsorption of ions of heavy metals in aqueous solutions utilizing montmorillonite

The adsorption process is an alternative treatment method used to remove heavy metals of industrials effluents. In the present paper, sorption processes nickel (II), copper (II) and lead in aqueous solutions, utilizing montmorillonite like substrates, including isotherms single metal solutions were studied. According X ray diffraction principal constituent quartz (SiO2) that surface area create most likely group Si-OH. This probably going absorb cations solutions. On other hand, dissociated (-S-O) a weak Lewis acid because polarization, chemisorption this case not favorable. Langmuir model, all cases, was found highest regression values (R2), therefore best fit. mineral showed ability take up tested order Ni > Pb Cu could be related valence hydration radius (IR) cations. presented results paper can for removal considerable amount effluent.
