Download or read book The Role of Iron Sulfides in Controlling Trace Heavy Metals in Anaerobic Sediments written by and published by . This book was released on 1977 with total page 424 pages. 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.

Download or read book Trace Element Speciation for Environment Food and Health written by L Ebdon and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing progress of science has shown that it is important for analytical scientists to determine not only the presence of particular elements, but also their species. There are many fields where this is applicable, and where there are a number of topics to be addressed. Developing separation and measurement systems for the many element species has tested the resourcefulness of analytical chemists over recent decades. A product of the EU sponsored Speciation 21 Network, this book presents a detailed review of the state-of-the-art of speciation issues in the occupational health, food and environment sectors, along with the main conclusions arising from discussions held during expert meetings. Topics covered include mercury and organotin compounds in the environment; factors affecting the health of workers; the importance of speciation of trace elements for health, and subsequent metabolism in the body; analytical methodologies; risk assessment; and legislation. Trace Element Speciation for Environment, Food and Health provides an insight into applied research in the speciation field and how it has become so important in all the fields represented. With its comprehensive coverage, it will be of particular interest to researchers in industry and academia, as well as government agencies and legislative bodies.

Download or read book Anaerobic Digestion written by Gavin Collins and published by Frontiers Media SA. This book was released on 2018-11-27 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is a naturally-occurring biological process in soils, sediments, ruminants, and several other anoxic environments, that cycles carbon and other nutrients, and converts organic matter into a methane-rich gas. As a biotechnology, AD is now well-established for the treatment of the organic fraction of various waste materials, including wastewaters, but is also increasingly applied for an expanding range of organic feedstocks suitable for biological conversion to biogas. AD applications are classified in various ways, including on the basis of bioreactor design; and operating parameters, such as retention time, temperature, pH, total solids (TS) and volatile solids (VS) contents, and biodegradability of substrates. AD is an attractive bioenergy and waste / wastewater treatment technology. The advantages of AD for waste treatment include: production of a useable fuel (biogas/methane); possibility of high organic loading; reduced carbon footprint; and suitability for integration into a wide variety of process configurations and scales. Specifically, two important, and developing, applications exemplify the potential of AD technologies: (1) the integration of AD as the basis of the core technologies underpinning municipal wastewater, and sewage, treatment, to displace less sustainable, and more energy-intensive, aerobic biological treatment systems in urban water infrastructures; and (2) technical innovations for higher-rate conversions of high-solids wastestreams, and feedstocks, for the production of energy carriers (i.e. methane-biogas, but possibly also biohydrogen) and other industrially-relevant intermediates, such as organic acids. Internationally, the research effort to maximize AD biogas yield has increased ten-fold over the past decade. Depending on the feedstocks, bioreactor design and process parameters, fundamental and applied knowledge are still required to improve conversion rates and biogas yields. This Research Topic cover aspects related to AD processes, such as the effect of feedstock composition, as well as the effect of feedstock pre-treatment, bioreactor design and operating modes, on process efficiency; microbial community dynamics and systems biology; influence of macro- and micro-nutrient concentrations and availability; process control; upgrading and calibration of anaerobic digestion models (e.g. ADM1) considering the biochemical routes as well as the hydrodynamics in such ecosystems; and novel approaches to process monitoring, such as the development, and application, of novel, and rapid diagnostic assays, including those based on molecular microbiology. Detailed full-scale application studies were also particularly welcomed.
