Adsorption of gemfibrozil (GF) from aqueous solution by highly/lowly graphitized carbon black (GCB-H/GCB-L) was investigated by batch and fixed-bed experiments. Results showed that the adsorption of GF onto GCB greatly depended on solution pH and graphitization of carbon. The pseudo-second-order kinetic model was found to be more appropriate in describing the adsorption processes of two GCBs. The adsorption equilibriums were well fitted with the Langmuir isotherm model, and GCB-H exhibited a higher adsorption capacity of 47.68 mg g−1 at 298 K, compared with GCB-L of 4.33 mg g−1. GCB-H achieved 69.76% GF removals in simulated water after 6 h, indicating its potential practicability. The GCBs were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR), and the results indicated that the [Formula: see text]-[Formula: see text] interaction was strongly involved in the adsorption. Thermodynamic studies further suggested that the adsorption of GF on GCB-H was exothermic, which could happen spontaneously at any temperature mainly through [Formula: see text]-[Formula: see text] interaction for physical adsorption on the surface of the plane.

Energy Distribution Functions

Different models which describe CO2 physisorption on a graphitized carbon black are analysed in the range 194·7 to 273·2 K. They are related to the thermodynamic functions and to adsorption energy distribution functions, which are obtained starting from experimental adsorption isotherms. This calculation, previously presented, is based on an extension of the Ross and Olivier method.
