Separating the Platinum Group Metals by Liquid-Liquid Extraction NEW PROCESS HAS POTENTIAL ECONOMIC ADVANTAGES OVER CONVENTIONAL SELECTIVE PRECIPITATION
To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a multitude of complex operations. A t present the final re.fining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as the degr...

15 صفحه اولBiorefining of platinum group metals from model waste solutions into catalytically active bimetallic nanoparticles
Bacteria can fabricate platinum group metal (PGM) catalysts cheaply, a key consideration of industrial processes and waste decontaminations. Biorecovery of PGMs from wastes is promising but PGM leachates made from metallic scraps are acidic. A two-step biosynthesis 'pre-seeds' metallic deposits onto bacterial cells benignly; chemical reduction of subsequent metal from acidic solution via the se...

WHAT promises to be the most complete and authoritative work on platinum and platinum deposits is about to be published in Geneva, Switzerland. The author, Louis Duparc, is professor of chemistry and petrology in the University of Geneva; the name of Marguerite N. Tikonovitch is announced as that of the associate author.' Professor Duparc has long been known as the writer of many papers on the ...
متن کاملSEPARATION OF NONHISTONE HIGH MOBILITY GROUP (HMG) FROM HUMAN LYMPHOCYTES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...
