Spectroscopic and thermal studies of bentonites from Ünye, Turkey
چکیده انگلیسی
Three bentonites from Turkey were investigated by X-ray diffraction (XRD), X-ray fluorescence (XRF), differential thermal analysis (DTA), thermogravimetric analysis (TG), Fourier transform infrared (FT-IR), magic angle spinning nuclear magnetic resonance (MAS NMR) and surface area measurement techniques. The XRD patterns showed that all three bentonite samples (B1, B2 and B3) were mainly composed of montmorillonite accompanied by cristobalite. In addition, albite appears in B3 sample studied. The heats of immersion of the bentonite samples (B1, B2 and B3) measured with a Calvet calorimeter at 30 °C in water were determined as −75.70, −54.69 and −68.22 J/g, respectively.
