Chen, Y., Huang, M., Chen, W., and Huang, B. (2012). "Adsorption of Cu(II) from aqueous solution using activated carbon derived from mangosteen peel," BioRes. 7(4), 4965-4975.


Effects of the mixing method of K2CO3 with the source biomass and thermal history on the properties of the mangosteen peel activated carbons (MSACs) were investigated. The one-step impregnation activation process was found to be remarkably effective in increasing the mesoporosity of the activated carbon (L-MSAC) as well as BET surface area (SBET) and total pore volume, compared to the solid-solid dry mixing method in a two-stage process. The better fit of Langmuir isotherm indicates a maximum adsorption capacity of Cu(II) to be 21.74 mg·g-1 for L-MSAC, which makes it a promising adsorbent for the removal of copper ion from aqueous solutions.
