An IGC Study of the Role of Washing Procedures on the Adsorption Properties of Activated Carbons (original) (raw)

Inverse gas chromatography (IGC) was used to study the influence of different washing treatments (acid, basic and combined washings) on the adsorption properties of two different activated carbons (steam-and chemically-activated). Chemical and textural characterization was carried out by the use of nitrogen adsorption, ICP-MS and temperature programmed desorption methods. The adsorption capacity and the interaction strength (sub-divided into dispersive and specific components) were determined by IGC.
