Fig. 2From: Preparation of carbon nanoparticles from activated carbon by aqueous counter collisionAdsorption isotherms of 2-h-activated tunicate cellulose (TC) carbon and 8-h-activated TC carbon. The open and closed symbols indicate the desorption and adsorption curves, respectively. V/mL (STP) g−1 indicates the absorption amount per 1 g of sample. P/P0 is relative pressureBack to article page
