Abstract The impregnation of granular activated carbon with the anionic surfactant sodium dodecylsulfate (SDS) was studied and influence on aurocyanide adsorption evaluated. Thermodynamic kinetic parameters were also determined. SDS improves gold by 10%, showing a cleansing effect surface which displayed in higher specific area. Specific pore volume average diameter did not undergo important ch...

MECHANISM AND KINETICS OF THE REDUCTION OF NITRIC OXIDE BY GRANULAR ACTIVATED CARBON INDUCED BY PdO/Al2O3 IN THE PRESENCE OF O2 by Tian Sang NO x and particulate matter are the main environmental hazards found in Diesel exhaust. In order to explore a novel method to remove NO„ as well as particulate matter, we examined the catalytic reduction of NO x with solid carbonaceous materials as a surro...
