    摘要： A system and method for the extraction of americium from radioactive waste solutions. The method includes the transfer of highly oxidized americium from an acidic aqueous feed solution through an immobilized liquid membrane to an organic receiving solvent, for example tributyl phosphate. The immobilized liquid membrane includes porous support and separating layers loaded with tributyl phosphate. The extracted solution is subsequently stripped of americium and recycled at the immobilized liquid membrane as neat tributyl phosphate for the continuous extraction of americium. The sequestered americium can be used as a nuclear fuel, a nuclear fuel component or a radiation source, and the remaining constituent elements in the aqueous feed solution can be stored in glassified waste forms substantially free of americium.

    摘要： A catalyst having high temperature (800.degree.-1050.degree. C.) stability and improved three-way automotive exhaust gas catalyst activity at high temperatures, comprising an outer catalytic coating of binary La-Pd oxide (La.sub.2 Pd.sub.2 O.sub.5 or La.sub.4 PdO.sub.7) calcined and supported on a catalyst-supporting substrate, the oxide being present in an amount to provide 15-150 g of Pd per cubic foot of the substrateA method of making binary La-Pd oxides useful as an automotive exhaust catalyst operative at high temperatures, comprising heating in an oxidizing atmosphere a mixture containing La compounds and Pd compounds in a La:Pd ratio of 1:1 or 4:1, the heating being staged to first heat slowly from about 50.degree. C. to start decomposition of the compounds and thereafter retaining the residue at an elevated temperature to stimulate growth of crystalline binary La-Pd oxides and to calcine the crystalline oxides.A method of making an automotive catalyst by suspending binary La-Pd oxides in a sol (preferably alumina sol) and depositing and fixing such sol suspension on a substrate coated with conventional washcoats.
