Na-bentonite has been studied extensively because of its strong adsorption capacity and complexation ability. In this work, surface area, total pore volume, mean pore diameter, TG, DTA, FT-IR and XRD were carried out in order to reveal the characteristics of natural Na-bentonite. XRD and FT-IR of natural Na-bentonite (China) and Cu-loaded Na-bentonite as a function of Na-bentonite dosage and temperature using batch technique were characterized in detail, respectively.
XRD of Cu(II)-loaded Na-bentonite at different solid/liquid ratio under the temperature of 10 °C.Figure optionsDownload as PowerPoint slideHighlights
► Adsorption of Na-bentonite for Cu(II) depends on dosage and temperature.
► Cu(II) cations replaced the original metal ions in Na-bentonite.
► The dosage and temperature have little influence on the shift of FT-IR and XRD.
