Agricultural by products
have proved to be promising raw materials for the production
of activated carbons because of their availability at a low price. They can
be used for the production of activated carbon with a high adsorption
ation.
In the physical activation, there are two steps: carbonization
step and activation step. The raw material is first carbonized under
No studies have been reported regarding the preparation of activated
carbon from grape stalk chemically activated with ZnCl2.
Therefore, the purpose of this work is to determine the optimal conditions
for preparing activated carbon from grape stalk with ZnCl2 activation.
The effects of activation temperature and time, impregnation
time and ratio on the yield and BET surface area of the activated carbon
were investigated.Moreover, the obtained activated carbonwas characterized
by proximate-ultimate analysis, BET surface area, iodine number,
surface functional group analysis by Boehm's titration and FT-IR
analysis, pHzpc, SEM-EDX and particle size distribution.
