Book Synopsis The Determination of 'total' Cyanide by the Ion-interaction Chromatographic Separation of Individual Metal Cyanide Complexes by :
Download or read book The Determination of 'total' Cyanide by the Ion-interaction Chromatographic Separation of Individual Metal Cyanide Complexes written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is described for the determination of a variety of metal cyanide complexes occurring typically in solutions and effluents derived from the processing of gold. The method employs reverse-phase ion-interaction chromatography using an acetonitrile eluent containing tetrabutylammonium hydroxide as the pairing reagent and a neutral phosphate buffer as the inorganic modifier. Individual metal complexes occurring in a process or tailings solution can be identified, and their cyanide content reliably estimated. The simultaneous determination of 'free' cyanide in waste waters, which allows the 'total' cyanide concentration to be estimated, is achieved by the conversion of the cyanide to the silver cyanide complex, followed by chromatographic separation. The precision of the procedure (relative standard deviation) for most of the complexes is acceptable, even at submicrogram-per-litre levels.

Book excerpt: The determination of a variety of metal complexes, typically occurring in solutions and effluents derived from the processing of gold, is described. The method makes use of reverse-phase ion-interaction chromatography, with an acetonitrile eluent containing tetrabutylammonium hydroxide as the pairing reagent and a neutral phosphate buffer as the inorganic modifier. Individual metal complexes occurring in a process or tailings solution can be identified and their cyanide content reliably estimated. The simultaneous determination of 'free' cyanide in waste waters, which allows an estimate of the 'total' cyanide concentration, was achieved by the conversion of the cyanide to the silver cyanide complex, chromatographic separation, and the use of calibration graphs.

Book Synopsis Handbook of Ion Chromatography by : Joachim Weiss
Download or read book Handbook of Ion Chromatography written by Joachim Weiss and published by John Wiley & Sons. This book was released on 2016-06-24 with total page 1576 pages. Available in PDF, EPUB and Kindle. Book excerpt: This three-volume handbook is the standard reference in the field, unparalleled in its comprehensiveness. It covers every conceivable topic related to the expanding and increasingly important field of ion chromatography. The fourth edition is completely updated and revised to include the latest developments in the instrumentation, now stretching to three volumes to reflect the current state of applications. Ion chromatography is one of the most widely used separation techniques of analytical chemistry with applications in fields such as medicinal chemistry, water chemistry and materials science. Consequently, the number of users of this method is continuously growing, underlining the need for an up-to-date reference. A true pioneer of this method, Joachim Weiss studied chemistry at the Technical University of Berlin (Germany), where he also received his PhD degree in Analytical Chemistry. In 2002, he did his habilitation in Analytical Chemistry at the Leopold-Franzens University in Innsbruck (Austria), where he is also teaching liquid chromatography. Since 1982, Dr. Weiss has worked at Dionex (now being part of Thermo Fisher Scientific), where he currently holds the position of Technical Director for Dionex Products within the Chromatography and Mass Spectrometry Division (CMD) of Thermo Fisher Scientific, located in Dreieich (Germany).
Book Synopsis Determination of Hydrogen Cyanide in Air by Ion Chromatography by : TW. Dolzine
Download or read book Determination of Hydrogen Cyanide in Air by Ion Chromatography written by TW. Dolzine and published by . This book was released on 1982 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a new procedure for the determination of hydrogen cyanide (HCN) concentrations in air. Airborne HCN is entrained in an impinger containing aqueous alkali and subsequently converted to sodium formate; the latter is quantitatively measured by ion chromatography. The collection procedure, reaction conditions, and chromatographic method are described. Interferences and the use of ion exchange resins for sample clean-up were investigated also. The precision and accuracy of spiked and air samples are presented.
Book Synopsis Chromatographic Separation and Determination of Stable Metal Cyanide Complexes in Gold Processing Solutions by :
Download or read book Chromatographic Separation and Determination of Stable Metal Cyanide Complexes in Gold Processing Solutions written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical analytical chemistry relied to a large extent on the physical separation of the individual elements or radicals prior to their identification and quantitative determination. With the advent of instrumental methods of analysis it became possible in many instances to detect and measure the concentration of elements by physical means without prior separation. Optical emission spectrometry, X-ray-fluorescence spectrometry, polarography, and activation analysis are examples of such techniques. In recent years, much effort has been directed towards 'speciation': the identification of the state of combination of the elements and their complexes as they exist in a sample, followed by quantitative estimation. This is of importance, for example, in the electroplating, electrowinning, water-treatment, and hydrometallurgical fields. Ion chromatography is a technique that can be used with success for some of this work. Chromatography as a method of separating species was first employed in 1906 by the botanist Tswett to separate plant pigments. The early chromatographic columns consisted of inorganic adsorbents such as alumina. Paper pulp was also used, to be followed by synthetic organic ion-exchange materials for chemical chromatographic separations. By the suitable choice of solvents and eluting agents, it has now become possible to separate certain chemical complexes with relative ease. It then remains to find a suitable method for the determination of the eluted species. Spectrophotometric or conductivity measurements are usually employed. The technique has been developed to such an extent that it can be used for small volumes of samples. The procedure has great potential in the South African mining context, not only for the better understanding and control of hydrometallurgical processes, but also for the analysis and monitoring of effluents. Pioneering work has been done at Mintek on the development and application of this technique in South Africa. Already several laboratories serving the mining industry have acquired similar equipment, and ion chromatography is becoming one of the accepted analytical procedures. Work on the determination of complexes other than cyanides is already in progress.
