چکیده
Abstract Fly ash as residue from coal combustion has potential for environmental applications an adsorbent water pollution treatment. Adsorption performance of fly depends on origin and chemical Modification by the treatment could increase adsorption capacity. In this paper, was alkali modified with NaOH solution at various concentrations (2 N, 4 6 10 N) a temperature 60 °C. The physical properties structural characteristics unmodified were studied Brunauer-Emmett-Teller (BET) surface area pore size analysis, also scanning electron microscope (SEM) analysis. results showed that modification area, average radius, total volume in ash. Unmodified be classified mesoporous materials exhibited type IV nitrogen adsorption-desorption isotherms H3 hysteresis loop according to classification International Union Pure Applied Chemistry (IUPAC). SEM observations revealed had rougher more porous structure than Alkali changed supports its application adsorbent.

Microstructural Characteristics of Geopolymers Based on Alkali-Activated Fly Ash
Aluminosilicate geopolymers with a high silica molar ratio have been prepared by mixing Croatian coal-ash (ASTM Class F) and sodium silicate solution (water glass, technical grade). The samples were cured at 85 °C for 8 h and 24 h in different experimental conditions. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDS) have been use...

Lead free, eco-friendly bismuth borate glasses doped with alkali oxides of composition xLi2O+(30-x)Na2O+55B2O3+15Bi2O3 (x = 5,10,15,20,25) were prepared by melt quenching technique. Amorphous nature of glasses was confirmed by X-ray diffraction. Density measurements were carried out at room temperature by standard principle of Archimedes with Xylene as an immersion liquid. The non-linear ...
