SO(2) and NH(3) Gas Adsorption on a Ternary ZnO/CuO/CuCl(2) Impregnated Activated Carbon Evaluated Using Combinatorial Methods.
Summary of "SO(2) and NH(3) Gas Adsorption on a Ternary ZnO/CuO/CuCl(2) Impregnated Activated Carbon Evaluated Using Combinatorial Methods."
Ternary libraries of 64 ZnO/CuO/CuCl(2) impregnated activated carbon samples were prepared on untreated or HNO(3)-treated carbon and evaluated for their SO(2) and NH(3) gas adsorption properties gravimetrically using a combinatorial method. CuCl(2) is shown to be a viable substitute for HNO(3) and some compositions of ternary ZnO/CuO/CuCl(2) impregnated carbon samples prepared on untreated carbon provided comparable SO(2) and NH(3) gas removal capacities to the materials prepared on HNO(3)-treated carbon. Through combinatorial methods, it was determined that the use of HNO(3) in this multigas adsorbent formulation can be avoided.

Medical and Biotech [MESH] Definitions
Ets-domain Protein Elk-1
A member of the ternary complex family of ets-related transcription factors that is regulated by MITOGEN-ACTIVATED PROTEIN KINASES including JNK MITOGEN-ACTIVATED PROTEIN KINASES; MITOGEN-ACTIVATED PROTEIN KINASE 1; MITOGEN-ACTIVATED PROTEIN KINASE 3; and P38 MITOGEN-ACTIVATED PROTEIN KINASES.
Carbonated Beverages
Drinkable liquids combined with or impregnated with carbon dioxide.
Ets-domain Protein Elk-4
A member of the ternary complex family of ets-related transcription factors that is regulated by MITOGEN-ACTIVATED PROTEIN KINASES such as EXTRACELLULAR SIGNAL-REGULATED MAP KINASES; and P38 MITOGEN-ACTIVATED PROTEIN KINASES.
Enterosorption
Adsorption of substances from the gastrointestinal tract onto an orally administered sorbent medium like activated charcoal. This technique is used to eliminate toxic and some biologically active substances and serves to modify the lipid and amino acid spectrum of the intestinal contents.
Estrenes
Unsaturated derivatives of the ESTRANES with methyl groups at carbon-13, with no carbon at carbon-10, and with no more than one carbon at carbon-17. They must contain one or more double bonds.
