The adsorption of methylene blue on montmorillonite from acid solutions

Popis výsledku v původním jazyce

The adsorption of methylene blue (MB) on montmorillonite from acidsolutions hasnot yet been studied in detail. In this paper the adsorption of this dye on Ca/SAz montmorillonitefrom 0.32, 0.80 and 1.60 M HCl solutions at ambient temperature and after 2 hours leaching wascarefully studied and evaluated. Under the above conditions the MB/SAz intercalates formed are practically insoluble. In contrast to the adsorption of methylene blue on montmorillonite from aqueous solutions, the adsorption from acid solutions consists of two adsorption waves. The intercalated samples from the first and second waves were studied using X-ray powder diffraction (XRD), FTIR, Vis spectroscopy, and scanning electron microscopy (SEM) equipped with a microprobe system. The adsorption of MB in the first wave is attributed to ion exchange of the dyecationic species (MB+, MB22+, H-aggregates, MBH2+ and H+) for the original interlayer cations of montmorillonite. The percentages of MBH2+ and H+ based on total adsor
