Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Investigations on the Platinum Metals, Vol. 7: Arc Spectra of the Platinum Metals (4500a to 9000a) Only three earlier investigations on the arc spectra of the platinum metals permit of a comparison of values with those given here. The first was by Professor Kayser, 3 who, in 1896, carefully measured the spectra throughout the range of wave lengths from ultra-violet to yellow. The second was by Eder and Valenta, 4 who, in 1910, extended Kayser's tables to the orange and red, but recorded only the stronger lines. The third was by Exner and Haschek, 5 who, in 1911 published their extensive observations on The Spectra of Elements at Normal Pressure. In this case, too, the data are incomplete, especially for the longer waves in the visible spectrum. In all three cases the wave-length values were based On the Rowland scale. With one exception; referred to below in the discussion on platinum, up to the present time no values for the arc spectra of the platinum metals have been determined relative to the new system of international standards adopted since 1910.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Investigation of the Platinum Metals: IV. Determination of Iridium in Platinum Alloys by the Method of Fusion With Lead The determination of iridium in platinum alloys by the method Of fusion with lead was devised by Deville and Stas 2 about 50 years ago. Since that time no critical investigation Of the method has been made to determine its reliability and accuracy. This method is the one most commonly used for the determination of iridium. As iridium alloys are now widely used commercially, it is im portant that a precise and dependable method for the analytical determination Of iridium be known. Consequently, a critical study Of the Deville and Stas method was undertaken at the Eu reau Of Standards as the first of a series Of investigations into the analytical methods for the metals Of the platinum group. The range per cent to 20 per cent was chosen for investigation. The lower limit represents platinum of commercial purity, while alloys containing a proportion Of iridium greater than 20 per cent are seldom used commercially.

Book excerpt: In 1901 the National Bureau of Standards (NBS) was founded to provide standard weights and measures and to be the national physical laboratory for the United States of America. The NBS conducted a lot of research in the fields of science and technology which were reported as "Scientific Papers." In 1988 the NBS became what we know now; the National Institute of Standards and Technology (NIST). This is one of those documents written by employees of the NBS.

Download or read book Chemistry of the Platinum Group Metals written by F.R. Hartley and published by Elsevier. This book was released on 2013-10-22 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.
