Descripción
In this work granular activated carbon has been chosen as an absorbent in order to investigate theCr(VI) reduced by adsorption experiments. Several batch chromium-sorption experiments were carried out using 0.25 gof granular activated carbon in 50mL aqueous solution containing approximately 70 and 140mgL^(-1) of Cr(VI) and Cr(III), respectively. Cr–Kb fluorescence spectra of Cr adsorbed in a carbon matrix and Cr reference materials were measured using a high-resolution Johann-type spectrometer. Based on evidence from the Cr–Kb satellite lines, the Cr(VI) reduction process has actually happened during metal adsorption by the activated carbon.
