An Investigation on the Adsorbent Material of Fly Ash

Abstract:

In this paper, the properties of fly ash were investigated. The particle size distribution, the fourier transform infrared spectroscopy (FTIR), the morphology, the surface area, pore volume, average pore diameter and the modification methods of fly ash were examined. The study indicated that the particle size of fly ash was about 0.2 µm, the particle shape was irregular. FTIR spectrums of fly ash modified were basically the same and the functional groups of fly ash were rarely. SEM of fly ash showed that the particles were similar to lamellar structure and the particle shape was irregular. The BET specific surface area of fly ash modified by H₂O₂was 41.63 m² /g. The fly ash of modified by H₂O₂ had better adsorption performance than other modified methods. The modification can effectively improve the adsorption performance of fly ash. The result indicated that the fly ash as adsorbent for wastewater treatment was feasible.
