Adsorption Of The Pesticides Bentazon, Carbofuran And 2,4-Dichlorophenoxyacetic Acid By Mesoporous Activated Carbons Prepared From Agriculture Waste
The adsorption of bentazon, carbofuran and 2,4-dichlorophenoxyacetic acid (2,4-D) from aqueous solution by activated carbons prepared from agricultural waste materials (palm oil fronds, banana stalks and date stones) was studied using batch and continuous processes. Mesoporous activated carbon...

| description |
The adsorption of bentazon, carbofuran and 2,4-dichlorophenoxyacetic acid
(2,4-D) from aqueous solution by activated carbons prepared from agricultural waste
materials (palm oil fronds, banana stalks and date stones) was studied using batch
and continuous processes. Mesoporous activated carbons with high surface areas
were prepared by physiochemical activation method consisting of potassium
hydroxide (KOH) impregnation and carbon dioxide (CO2) gasification. Various
parameters, such as activation temperature, activation time and chemical
impregnation ratio (IR= wKOH /wchar), which have influence on the structure and
performance of the activated carbons, were examined. The optimum conditions
obtained for the prepared activated carbons using response surface methodology
were 750 oC at 3 h and impregnation ratio of 3.75 for palm oil fronds activated
carbon (PFAC), 740.5 oC at 1.08 h and impregnation ratio of 2.3 for banana stalk
activated carbon (BSAC), and 850 oC at 2.97 h with impregnation ratio of 3.75 for
date stone activated carbon (DSAC). |
