Title StatementPreparation of activated carbons from unburnt coal in bottom ash with KOH activation for liquid-phase adsorption by Ruey-Shin Juang and 3 others
Physical Descriptionpages 1097-1102 computer file; text; 666kb
Summary, Etc.In this work, unburnt coal (UC) in bottom ash from coal-fired power plants was soaked in KOH solution and activated for 1 h at 780 C. The yield of activated carbons varied from 47.8 to 54.8% when the KOH/UC weight ratio changed from 2 to 4. Pore properties of these activated carbons including the BET surface area, pore volume, pore size distribution, and pore diameter were characterized based on N2 adsorption isotherms. It was shown that the isotherms for the adsorption of methylene blue, acid blue 74, and 4- chlorophenol from aqueous solutions on these activated carbons at 30 C were well fitted by the Langmuir equation (correlation coefficient r2 > 0.9968). The adsorption capacities of methylene blue, acid blue 74, and 4-chlorophenol were obtained to be 2.40–2.88, 0.57–1.29, and 2.34–5.62 mmol/g, respectively. Moreover, the adsorption kinetics could be suitably described by the Elovich equation.04 En
