Available in PDF, EPUB and Kindle. Book excerpt: The study of the kinetics of oxidation of the ferrous monosulfide mackinawite and the fate of the associated heavy metals are important to a better understanding of the processes and mechanisms controlling the release, transport and retention of heavy metals in natural aquatic systems. This project undertook a detailed study of several selected aspects of the aqueous chemistry of heavy metals and of the oxidative dissolution of FeS(s) and the fate of associated heavy metals both during and after the oxidation reaction. The material is organized into sections dealing with the basic aqueous chemistry of iron and sulfur, silver, cadmium, adsorption models, experimental methodology, results and discussion.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The kinetics of the non-oxidative dissolution in acids of the iron sulphides FeS, Fe-FeS, and Fe9S10 were studied by the use of rotating-disc electrodes of the various compounds. It was found that the rates of dissolution vary by orders of magnitude with changes in surface potential. The dissolution rates depend on non-integral orders of hydrogen-ion concentration, which in turn vary with potential. A mechanism based on the following premises is proposed to explain the kinetics of dissolution of the iron sulphides. 1. Only an FeS compound that is exactly stoichiometric dissolves in accordance with the accepted theory of ionic charge transfer. 2. Any non-stoichiometric iron-deficient iron sulphides must be reduced to exactly stoichiometric FeS before spontaneous non-oxidative dissolution can occur. The dissolution of Fe9S10 and slightly iron-deficient FeS compounds under open-circuit conditions occurs only when an oxidation reaction (usually the oxidation of hydrogen sulphide to elemental sulphur) can provide the electrons necessary for the production of exactly stoichiometric FeS. The establishment of such a mixed-potential system is the reason for the induction period that occurs during the dissolution of pyrrhotites in acids.

Download or read book Mineral Water Interface Geochemistry written by Michael F. Hochella and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 23 of Reviews in Mineralogy and accompanying MSA short course covers chemical reactions that take place at mineral-water interfaces. We believe that this book describes most of the important concepts and contributions that have driven mineral-water interface geochemistry to its present state. We begin in Chapter 1 with examples of the global importance of mineral-water interface reactions and a brief review of the contents of the entire book. Thereafter, we have divided the book into four sections, including atomistic approaches (Chapters 2- 3), adsorption (Chapters 4-8), precipitation and dissolution (Chapters 9-11), and oxidation-reduction reactions (Chapters 11-14).

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of iron-sulfide degradation in concrete aggregates has proven to be a major problem in concrete infrastructure, causing insufficient concrete durability and extensive structural damages which include expansion, cracking, and popouts. Over the years, there have been various reports of iron-sulfide minerals like pyrite and pyrrhotite causing oxidation reactions and leading to extensive residential concrete foundation damage in Connecticut and Quebec, Canada. In many of these cases, damages have been so serious to the structural integrity of the structures that immediate remediation has been required to repair the deterioration. The issue is not well documented despite reports of damage in the United States, Canada, and parts of Europe. Currently, there are limited existing standardized testing methods or mitigation strategies for the presence of iron-sulfide minerals in concrete aggregates because the mechanisms by which degradation occurs are not fully understood. The objective of this research is to experimentally measure the kinetics of iron-sulfide oxidation reactions in dissolution systems with oxidizing agents and analyze existing dissolution rate data available to assist in determining the factors that influence the deterioration of aggregates used in concrete infrastructure.
