The performances of three wood-based activated carbons as adsorbents of hydrogen sulfide were evaluated by dynamic breakthrough testing. The subsequent products of H 2 S oxidation on the carbon surfaces were analyzed. The adsorbents were studied using sorption of nitrogen, thermal analysis, Boehm ti

The sorption of hydrogen sulfide was studied on activated carbons of various origins by means of inverse gas chromatography at infinite dilution. The conditions of the experiment were dry and anaerobic. Prior to the experiments the surface of some carbon samples was oxidized using either nitric acid
The single adsorption of cadmium and copper from aqueous solutions has been investigated on Darco 12ยฑ20 mesh granular activated carbon for a wide range of experimental conditions: pH, metal concentration and carbon concentration. The results showed the efยฎciency of the activated carbon as sorbent fo
The effect of the adsorption properties and surface chemistry of activated carbons on the adsorption of germanium (IV) from dilute aqueous solutions (50 ppm) was investigated. A large number of activated carbons were obtained by activating three precursors, one coal and two lignocellulosic chars, wi
