چکیده انگلیسی
The objective of the present research was to synthesize, characterize and to investigate adsorption of nitrate from synthetic nitrate solution by Ca-Al-Cl HTlc. In the present study Ca-Al-Cl HTlc was synthesized by co-precipitation method and was characterized using SEM, XRD, FTIR and TGA-DSC. To assess the practical usefulness, a detailed removal study of nitrate was carried out. The removal of nitrate was 84.6% under neutral condition using 0.35Â g of adsorbent in 100Â mL of nitrate solution having initial concentration of 10Â mg/L. Adsorption kinetic study revealed that the adsorption process followed first order kinetics. Adsorption data were fitted to linearly transformed Langmuir adsorption isotherm with R2 (correlation coefficient)Â >Â 0.99. Thermodynamic parameters were also calculated to study the effect of temperature on the removal process. In order to understand the adsorption type, equilibrium data were tested with Dubinin-Radushkevich isotherm.
