Surface modification, characterization and adsorptive properties of a coconut activated carbon

Study on the pore structure and oxygen-containing functional groups devoting to the hydrophilic force of dewatered lignite

“…The adsorption capacity of adsorbent on the surface of solid is associated with its physical and chemical properties. [15,16]. The adsorption mechanism of water vapor on the surface of coal has been studied by some researchers and they considered that the interaction bonds between water and coal were mainly free water held by physicochemical forces, adsorbed water determined by hydrogen bonds, and chemically bonded water [17].…”

Preparation and Characterization of Sisal Fiber-based Activated Carbon by Chemical Activation with Zinc Chloride

“…purification process, removal of organic and metals, and so on), their adsorption capability is shown to be largely controlled by their pore structure, surface area and pore volume. [1][2][3] By IUPAC definition, micropores are pores with radii r < 2 nm, mesopores 2 < r < 50 nm, and macropores r > 50 nm. In principle, the activation methods of preparing activated carbons can be divided into two categories: chemical activation and physical activation.…”

Removal of total organic carbon (TOC) residues from power plant make-up water by activated carbon

“…Carbons A, B and C had constant total pore volume during the pilot run. The decrease in the AC volume has been attributed in the literature to the pore blockage [31]. However, in our study pore volumes had no clear correlation to the TOC removal.…”
