“…This had resulted in the development of porosity from 23.6 to 66.0%. For the activated carbon prepared from the extracted rockrose by CO 2 activation, Pastor-Villegas et al (4) reported that the total porosity of the sample was 62.9%, which was close to that of the palm-shell activated carbon prepared in this study.…”

“…These renewable agricultural solid wastes are cost-effective alternatives to more expensive and polluting precursors like coal in the production of activated carbon. Some agricultural solid wastes, such as rockrose (4), kraft lignin (5), apricot stone (6, 7), walnut shell (8), and almond shell and hazelnut shell (9) have been successfully converted into activated carbons in the laboratories.…”

Abstract. The adsorption of Fe(II) from aqueous solutions by acid modified jackfruit wood sawdust biosorbent was investigated in a batch adsorption system. The experiment conducted at room temperature and pH 5 resulted adsorption behaviour of chemical modified Jackfruit wood sawdust biosorbent. The removal of Fe(II) has been found to be the function of initial Fe(II) concentration, acid type and acid concentration. The best removal was at low Fe(II) initial concentration, the higher initial concentration resulted on lower adsorption. Untreated jackfruit wood sawdust has the highest adsorption efficiency, followed by acetic acid, citric acid and tartaric acid modified jackfruit wood sawdust. The maximum uptake capacity of Fe (II) ion was 1.05 mg/g by untreated jackfruit wood sawdust.

“…It is so in particular for C900, which suggests that at 900°C pore shrinkage occurs, decreasing the porosity accessible to N 2 at −196°C. A microporosity decrease at high heat treatment temperatures was reported elsewhere (Neely 1981;Pastor-Villegas et al 1993;Gómez-Serrano et al 1996) and connected with lateral growth and increase in planarity of layer planes (Masters and McEnaney 1984). Second, for the ACs S BET , W 0 and V mi vary by S > A > CD.…”

Development of activated carbon from vine shoots by physical and chemical activation methods. Some insight into activation mechanisms

et al. 2011

Activated carbons (ACs) are prepared from vine shoots (VS) by the method of physical activation in air, CO 2 and steam atmospheres and by the method of chemical activation with H 3 PO 4 , ZnCl 2 and KOH aqueous solutions. The ACs were characterized texturally by N 2 adsorption at −196°C, mercury porosimetry, and density measurements. The method of chemical activation has been proved to be more effective than the method of physical activation to prepare ACs with a well-developed porosity. ACs with high micro-and mesopore volumes are prepared with ZnCl 2 and H 3 PO 4 . Using ZnCl 2 , the volume of micropores is 0.62 cm 3 g −1 and the volume of mesopores is 0.81 cm 3 g −1 . A greater development of macroporosity is obtained by KOH activation. The volume of macropores is as high as 1.13 cm 3 g −1 for the resulting AC. Yield of the process of preparation of the ACs is low for the method of chemical activation. Some insights into the performance of the activating agents in the activation process are provided.
