Download or read book Iron Oxy Hydroxide Minerals and Their Application for Phosphate Removal from Wastewater Via Adsorption and for Prebiotic Reactions on the Early Earth written by Erika Flores and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron (oxy)hydroxide minerals are chemically reactive, possess adsorptive properties and have been shown to be involved in a variety of reactions. These minerals can occur naturally in the environment and can be synthesized in the lab. In this work, iron minerals were studied for their applications to phosphate removal from wastewater and prebiotic reactions on the Early Earth (anoxic environment before existence of life). Phosphorus (P) is a fundamental element for biochemistry and life as we know it. In nature it exists as its oxidized form, phosphate (PO43-), it is a structural component in both DNA and RNA and is an essential nutrient for humans, animals and plants. The P cycle, a biogeochemical cycle, allows P to move through the lithosphere, hydrosphere, and biosphere yet in the early Earth, these processes would not have been the same and PO4 would have been less available for reactions due to its insolubility. It could have been possible, however, for PO4 to have been concentrated long enough for changes in the environment to occur which could have allowed PO4 to be released and become more available. Although PO4 is essential to life, excess loading in the environment due to anthropogenic activities such as agricultural runoff, urban runoff, and wastewater discharge can lead to nutrient pollution. Elevated amounts of PO4 in bodies of water has detrimental effects to human health and the environment; resulting in contamination of drinking water and death of aquatic life. Nutrient pollution is a worldwide problem and it is imperative to deal with the problem at the source and this necessitates new technologies for treatment in small-scale wastewater treatment systems.In this work, several studies were conducted to synthesize iron (oxy)hydroxide minerals at various iron redox state (0% Fe2+ to 100% Fe3+) and pH (6 to 9) and anoxic/oxic conditions to test their reactivity in prebiotic reactions and their adsorption of PO4 for concentration of PO4 on the early Earth and for P-removal in septic systems. These studies demonstrated that iron (oxy)hydroxides are highly reactive (producing amino acids and Îł-hydroxy acids) and efficiently adsorb phosphate ( > 90%) at a range of experimental conditions. Geochemical gradients such as redox, pH and temperature had an effect on reactions. Mechanism and kinetic experiments are needed to better understand the adsorption reaction system so that proper implementation techniques to septic systems to enhance P-removal can be sought. Overall, it is important to further study iron (oxy)hydroxide minerals as they can be applicable to a variety of fields including environmental engineering and astrobiology.

This book was released on 2010-09-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Flotation Reagents: Chemistry, Theory and Practice: Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths. It examines separation methods whose effectiveness is limited when using conventional treatment processes and considers commercial plant practices for most oxide minerals, such as pyrochlore-containing ores, copper cobalt ores, zinc ores, tin ores, and tantalum/niobium ores. It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits. In addition, case studies of flotation and beneficiation in countries such as Canada, Africa, Russia, Chile, and Saudi Arabia are presented. This book will be useful to researchers, university students, and professors, as well as mineral processors faced with the problem of beneficiation of difficult-to-treat ores. Looks at the theoretical aspects of flotation reagents Examines the practical aspects of using chemical reagents in operating plants Provides guidelines for researchers and engineers involved in process design and development

This book was released on 2011-05-01 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Together, minerals, rocks, and fossils communicate much about Earth’s history. Much more than ornaments on a landscape, minerals and rocks are significant components of the planet’s foundation, while fossils contain clues as to the various life forms that once inhabited the planet. Readers are invited to take a closer look at the materials that have, in many ways, facilitated life, and to explore the types and categories of minerals, rocks, and fossils alike.

Book excerpt: Biogeochemistry: An Analysis of Global Change, Fourth Edition, considers how the basic chemical conditions of the Earth, from atmosphere to soil to seawater, have been, and are being, affected by the existence of life. Human activities in particular, from the rapid consumption of resources to the destruction of the rainforests and the expansion of smog-covered cities, are leading to rapid changes in the basic chemistry of the Earth. The new edition features expanded coverage of topics, including the cryosphere, the global hydrogen cycle, biomineralization and the movement of elements across landscapes and continents by organisms and through global trade. The book will help students and researchers extrapolate small-scale examples to a global level. With cross-referencing of chapters, figures and tables, and an interdisciplinary coverage of the topic, this updated edition provides an excellent framework for examining global change and environmental chemistry. Includes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry Synthesizes the global cycles of carbon, nitrogen, phosphorous and sulfur, and suggests the best current budgets for atmospheric gases such as ammonia, nitrous oxide, dimethyl sulfide, and carbonyl sulfide Features updated literature references and expanded coverage of topics, including the cryosphere, the global hydrogen cycle, biomineralization and the movement of elements across landscapes and continents by organisms and through global trade
