“…The absorbance peak at 1222 cm −1 is C-O stretching vibrations in ester, ether, and phenol groups. The band at around 879 cm −1 can be due to C-H out of plane bending vibration in an aromatic ring [3,7]. Scanning electron micrograph of the AC3500 produced at the optimum conditions is presented in Fig.…”

Activated carbon is a complex and crude form of graphite. Compared to graphite, activated carbon exhibits an unusual imperfect structure that is tremendously porous ranging from nanopore to milipore sizes. Its graphitelike structure yields the carbon its very large surface area which takes a great advantage to adsorb a wide range of substances. Although the production of activated carbon from the raw materials such as coal and coal tar pitch prevails, its production from agricultural wastes is possible. In this study the canola straw is considered as a potential activated carbon source. The examined samples were obtained by chemical activation. New kind of carbons were characterized by elemental analysis, the Brunauer-Emmett-Teller (BET) surface area, scanning electron microscopy (SEM) images, and the Fourier transform infrared spectroscopy (FTIR). Besides, the effect of experimental parameters on chemical and pore properties of the activated carbon materials was modeled and optimized.

“…The band at 1620 cm −1 can be ascribed to C-C aromatic ring stretching vibration [24]; this band of BFAC-H 3 PO 4 and BFAC-H 4 P 2 O 7 was much higher than BFAC-ZnCl 2 and BFAC-(NH 4 ) 2 HPO 4 , indicating that phosphoric acid and pyrophosphate have a certain aromatization effect. The strong peak at 1080 cm −1 indicates the presence of alcohol groups, which indicates the presence of polysaccharides [25].…”

In order to explore the influence of different activators on the structure and properties of the prepared activated carbon, bamboo fiber-based activated carbons (BFACs) were prepared by four activators of phosphoric acid, pyrophosphoric acid, zinc chloride, and diammonium biphosphate (BFAC-H3PO4, BFAC-H4P2O7, BFAC-ZnCl2, and BFAC-(NH4)2HPO4) and BFACs adsorption performance and electrochemical properties were investigated. The main conclusions were: the specific surface area of the four BFACs varies greatly, among which BFAC-ZnCl2 was the highest, at 1908.5074 m2/g, and BFAC-(NH4)2HPO4 was the lowest, at 641.5941 m2/g. In terms of the pore structure, BFAC-H3PO4 and BFAC-H4P2O7 are mainly mesopores and BFAC-ZnCl2 and BFAC-(NH4)2HPO4 are mainly micropores. The BFAC-ZnCl2 sample had the largest specific capacitance, with a specific capacitance of 121.2730 F/g at a current density of 0.2 A/g, with a small internal resistance and good electrochemical reversibility and capacitance performance. The adsorption properties were better for BFAC-ZnCl2 and BFAC-H3PO4 and the adsorption amounts were 648.75 and 548.75 mg/g, respectively.

“…The surface area for DPAC was 886.31 m 2 /g whereas the surface area for DP was not available since there was no pore identified. Surface area obtained was considered average compared to ACs derived from Egyptian wood of 603 m 2 /g (Ilnicka et al, 2020), durian seed of 980.62 m 2 /g (Ab Razak et al, 2015) and spent mushroom compost of 1419.11 m 2 /g (Karadirek and Okkay, 2018). The average pore diameter for DPAC was 2.57 nm which belong to mesopores region according to the IUPAC classification.…”

Physiochemical activation consists of heat treatment coupling with CO2 gasification and KOH chemical treatment were applied in preparing durian peel based activated carbon (DPAC) to remove basic dye, malachite green (MG) from aqueous solution. Several parameters namely, effect of initial MG concentration as well as contact time, solution temperature and initial solution pH were carried out in this study. Characterization study revealed that DPAC pose high BET surface area which is 886.31 m2/g and its surface was found to be mesoporous in nature with heterogeneous type of pore structures. Eight isotherms and four kinetic models were utilized and it was revealed that the adsorpttion system followed Freundlich isotherm and pseudo-first order (PFO) kinetic model. Mechanism study using intraparticle diffusion and Boyd plot confirmed that adsorption of MG onto DPAC was controlled by the film-diffusion mechanism. Thermodynamic study indicated that the adsorption system was exothermic, spontaneous, feasible and governed by physical-type of adsorption.
