dc.description.abstract | In this study, phosphate (P) removal from aqueous solutions by hydrocalumite was investigated using batch experiments and model analyses. The maximum phosphate removal capacity was determined to be 127.53mgP/g under the given experimental conditions (hydrocalumite dose=0.05g/L, initial P concentration=2-20mgP/L, reaction time=24h). Model analyses showed that the Elovich model was most suitable for describing the kinetic data, whereas the Redlich-Peterson model provided the best fits to the equilibrium data. Furthermore, phosphate removal by hydrocalumite was not sensitive to pH changes between 4.0 and 11.0. A thermodynamic analysis indicated that phosphate removal by hydrocalumite increased with a rise in temperature from 15 to 45 degrees C, suggesting that the removal process was spontaneous and endothermic (H degrees=32.05kJ/mol, S degrees=112.86J/K/mol, G degrees=-0.47 to -3.86kJ/mol). The phosphate removal capacity in stream water (5.40-17.25mgP/g) was also lower than that in a synthetic P solution (6.86-27.51mgP/g) under the given experimental conditions (initial P concentration=2mgP/L, hydrocalumite dose=0.05-0.3g/L, reaction time=24h). Such a result could possibly be ascribed to the presence of carbonate ions (CO32-) in the stream water, which could interfere with phosphate removal by hydrocalumite through the precipitation of calcium carbonate (CaCO3). | - |
