摘要：

The adsorptive properties of a selection of carbons produced by the chemical treatment of lignite and pear have been investigated. Adsorption of phenol, basic red dye, copper ions and NO2 by the carbons is assessed. Adsorption equilibrium isotherms were plotted to obtain Langmuir constants for each system. Adsorption capacity of each carbon depends on the method of activation. Gas sorption and mercury porosimetry were the methods used to study the micro, meso and macropore volumes, surface areas and pore radius distributions of the carbon samples.
