Book Description
Methods based on atomic-absorption spectrophotometry, and involving various techniques for dissolution and measurement of the sample, have been developed for the determination of trace elements in coal. Non-volatile elements are determined by flame atomic absorption, and vanadium by electrothermal atomization of a solution, after ashing of the sample and dissolution of the residue with acid. Arsenic, selenium, bismuth, and tellurium are determined by hydride generation on a separate portion of the sample that has been ashed in the presence of sodium carbonate and fused with sodium peroxide. The laboratory methods are detailed in the appendices.

Book Description
Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.

Book Description
This Second edition of the flow injection analysis (FIA) text which has become a standard in the field in four languages, is written by two pioneers in the field, who have themselves discovered many of the techniques and designed much of the equipment employed in FIA. Newly revised to account for the many recent developments in FIA, this book presents the state-of-the-art in FIA theory, techniques, and future trends. Specific topics covered include continous-flow analyzers, chemical kinetics in an FIA system, theory of dispersion related to FIA, single-line FIA manifolds, FIA determinations based on separation processes, commercially available flow-injection analyzers, the FIA laboratory--a microconduit-based pedagogical system, review of the flow-injection literature, and flow injection analysis now and in the future.
