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...

Adsorption is a fundamental process in the physicochemical treatment of municipal wastewaters, a treatment which can economically meet today's higher effluent standards and water reuse requirements. Activated carbon is the most effective adsorbent for this application. Expanded-bed contact systems permit most efficient use of granular carbon for waste treatment. The adsorption process is enhanc...

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
