Abstract
A geopolymer is an eco-friendly porous inorganic material that can be used as dye adsorbents in wastewater treatment. It is formed upon dissolution of aluminosilicate in the presence of a high basic activating solution. This research aimed to synthesize and characterize fly ash based geopolymer and to examine the use of the synthesized geopolymer to adsorb brilliant green dye from aqueous solution. The geopolymer was characterized by X-ray Fluorescence (XRF), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectrometry (FTIR). The results demonstrated that the suitable dosage of fly ash based geopolymer was 2 g/L, the contact time was 15 minutes with the adsorption efficiency of 97.35 percent for the initial brilliant green dye concentration of 100 ppm. The isotherm of brilliant green dye adsorption by fly ash based geopolymer was consistent with the Langmuir isotherm. The kinetic adsorption corresponded well to the pseudo- second order model. Furthermore, the positive enthalpy value and the negative Gibbs’s free energy indicated that the adsorption process was an endothermic and spontaneous reaction, respectively. The results from this study demonstrated that the geopolymer material synthesized from low-cost materials had potential applications for water treatment and remediation of hazardous dye based pollutants.
