dc.description.abstractPurolite AC-20 and Norit RB 0.8CC activated carbons impregnated with AgNO3 were used for the removal of CN– and Ag–CN complex from model wastewater. The formed Ag0 centers were approved by scanning electron microscopy micrographs and X-ray powder diffraction data. The degree of Ag0 participating in CN– sorption varied from 100 to 45% on AC-20/Ag and from 100 to 73% on RB 0.8CC/Ag, by varying [CN–]/[Ag] in the initial solution from 2.0 to 19.2. The Freundlich isotherm and Fleming kinetic models were consistent with the experimental data. The KF values for the CN– adsorption on AC-20/Ag and RB 0.8CC/Ag increased by a factor of 1.2 and 1.5, but they lowered for Ag–CN adsorption by a factor of 4.1 and 2.1, respectively, as compared to that of plain activated carbons. The removal of 90% cyanides is appropriate by combining two batches from activated carbon: impregnated, mainly for the removal of CN–, and plain, removing the rest of Ag–CNen
