Abstract
The objective of this research is to improve the adsorption capacity of adsorbent made from MSWI (Municipal Solid Waste Incinerator) fly ash by surface oxidation. Used oxidation agents were $HNO_{3}$, $H_{2}SO_{4}$ and $(NH_{4})_{2}S_{2}O_{8}$. These agents can modify the surface property of an adsorbent such as specific surface area, pore volume, and functional group. The surface structure was studied by BET method with $N_{2}$ adsorption. The acid value and base value were determined by Boehm's method. The adsorption properties were investigated with benzene and MEK (Methylethylketone). According to the results, the specific surface area of the adsorbent was increased from 309.2 $m^{2}$/g to 553.2 $m^{2}$/g by $HNO_{3}$ oxidation. But $H_{2}SO_{4}$ and $(NH_{4})_{2}S_{2}O_{8}$ oxidation was decreased slightly. After Oxidation, surface acid value increased, but base value decreased. FAA-N shows the highest acid value. The content of oxygen increased greatly and oxygen group was created on the adsorbent surface. The surface oxidation improved the adsorbing capacity for MEK. The amount of adsorbing MEK was increased from 189 $m^{2}$/g to 639 $m^{2}$/g by $HNO_{3}$ oxidation.
