This book was released on 2018-06-15 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field screening method for the determination of elemental mercury in environmental soil samples involves the thermal desorption of the mercury from the sample onto gold and then the thermal desorption from the gold to a gold-film mercury vapor analyzer. This field screening method contains a large number of conditions that could be optimized for the various types of soils encountered. In this study, the conditions were optimized for the determination of mercury in silty clay materials, and the results were comparable to the cold-vapor atomic absorption spectrophotometric method of determination. This paper discusses the benefits and disadvantages of employing the field screening method and provides the sequence of conditions that must be optimized to employ this method of determination on other soil types.

Available in PDF, EPUB and Kindle. Book excerpt: Dr. Paul H. Ramses Gouda, is a globally renowned chemist who authored several science books and papers. He has been credited with the foundation of several analytical laboratory procedures utilizing Atomic Absorption and Inductively Coupled Plasma for ultra trace analysis of As, Se, Sb &Hg. These Methods were officially adopted by EPL and by other agencies, and as routinely practiced in the scientific arena they were named after him. The author, who first attended medical school before specializing in analytical chemistry and pharmacological research, has acquired two doctorates. His contributions to the scientific community include a recent paper on the unique concept of the duplication and manipulation of neurological compounds to trigger a natural and optimum physiological response. Tour the authors books at and his book-signing sessions at www.goudabooks.com and his science project, scheduled symposiums & seminars at www.optimumgreen.com This book offers a complete coverage of mercury analysis methodology. An analytical laboratory reference, a chemist manual, and a university textbook. A must for every library.

This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure for determining mercury in liquid samples by cold vapor flameless atomic absorption spectroscopy was developed. The optimum parameter values were determined and mercury standard storage conditions investigated. The effect and tolerance levels of twenty-seven ions, including those ions common to Tank Farm Operations and the Synthetic Wastes, were measured. Standard deviation for the procedure is less than 1%. The procedure can be used to determine mercury at the part per billion level in any liquid sample, a thousand-fold increase in sensitivity over current flame techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The protocols for Methods 7470 and 7471 in the SW-846 methods manual are designed for the cold-vapor atomic absorption spectrometric (CV-AAS) determination of total mercury in aqueous (extracts, wastewater, ground water, etc.) and solid (soils, sediments, sludges, etc.) materials, respectively. Aqueous samples are digested with a combination of nitric and sulfuric acid plus permanganate and persulfate solutions at elevated temperature; solid samples are heated either on a steam bath with aqua regia and permanganate, or in an autoclave with sulfuric acid, nitric acid and permanganate. The mercuric ions in the digests are then reduced with hydroxylamine, and the elemental mercury is aerated into the AAS cell, either in a closed (recirculating) or an open system, where the absorption at 253.7 nm is determined.
