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.

Download or read book Earth Materials written by Dexter Perkins and published by CRC Press. This book was released on 2019-07-24 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a large and growing need for a textbook that can form the basis for integrated classes that look at minerals, rocks, and other Earth materials. Despite the need, no high-quality book is available for such a course. Earth Materials is a wide-ranging undergraduate textbook that covers all the most important kinds of (inorganic) Earth materials. Besides traditional chapters on minerals and rocks, this book features chapters on sediments and stratigraphy, weathering and soils, water and the hydrosphere, and mineral and energy deposits. Introductions to soil mechanics and rock mechanics are also included. This book steers away from the model of traditional encyclopedic science textbooks, but rather exposes students to the key and most exciting ideas and information, with an emphasis on thinking about Earth as a system. The book is written in such a manner as to support inquiry, discovery and other forms of active learning. All chapters start with a short topical story or vignette, and the plentiful photographs and other graphics are integrated completely with the text. Earth Materials will be interesting and useful for a wide range of learners, including geoscience students, students taking mineralogy and petrology courses, engineers, and anyone interested in learning more about the Earth as a system.
