Utilization of zinc chloride for surface modification of activated carbon derived from Jatropha curcas L. for absorbent material

View Article: PubMed Central - PubMed

ABSTRACT

The objective of this research is to produce the low-cost activated carbon from Jatropha curcas L. by chemical activation using zinc chloride ZnCl2. The effects of the impregnation ratio on the surface and chemical properties of activated carbon were investigated. The impregnation ratio was selected at the range of 1:1–10:1 for investigation. The optimum conditions resulted in an activated carbon with a carbon content of 80% wt, while the specific surface area evaluated using nitrogen adsorption isotherm corresponds to 600 m2/g.

f0005: FTIR spectra of surface modification of activated carbon derived from Jatropha curcas.

Mentions: Fig. 1 shows that the functional groups of activated carbon differ significantly from those of pyrolyzed char [4], [5], [6], [7], [8]. The spectrum from char at 3393 cm−1 indicated the presence of the –OH group of phenol. The methylene group is detected by –CH stretching at a wave number of 2924 cm−1. The aldehyde group of –O–CH3 is found around 2853 cm−1. Strong bands at 1641 cm−1 indicate C–O stretching of carboxyl or carbonyl groups. Methyl or amine groups are shown by a peak around 1385–1380 cm−1. The band from 1200 to 1000 cm−1 is the fingerprint of syringyl units. Aldehyde and derivatives of benzene are detected by peaks at 875 and 761 cm−1.
