This book was released on 2017-01-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: A substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties in estuaries and the coastal and open ocean has occurred during the last decade. We are making progress on finding the actual chemical compounds or phenomena responsible for DOM’s optical properties. Ultrahigh resolution mass spectrometry, in particular, has made important progress in making the key connections between optics and chemistry. But serious questions remain and the last major special issue on DOM optics and chemistry occurred nearly 10 years ago. Controversies remain from the non-specific optical properties of DOM that are not linked to discrete sources, and sometimes provide conflicting information. The use of optics, which is relatively easier to employ in synoptic and high resolution sampling to determine chemistry, is a critical connection to make and can lead to major advances in our understanding of organic matter cycling in all aquatic ecosystems. The contentions and controversies raised by our poor understanding of the linkages between optics and chemistry of DOM are bottlenecks that need to be addressed and overcome.

Download or read book Advances in the Physicochemical Characterization of Dissolved Organic Matter written by Fernando Rosario-Ortiz and published by ACS Symposium. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of dissolved organic matter (DOM) has fascinated scientists and engineers for at least 60 years - from the initial efforts focused on measuring the concentrations of carbon in marine and aquatic systems, to the discovery of the role of DOM in the formation of disinfection byproducts, all the way to the new emphasis on the detailed understanding of the different functional groups and basic structural features which are the basis for the physicochemical properties of the material. After 50 years of work in the area, there are still many questions regarding DOM. The study of dissolved organic matter (DOM) has fascinated researchers in different fields of science and engineering for many decades. The impact that DOM has on a wide array of environmental processes has resulted in the development of a multidisciplinary community of researchers all focusing on using different analytical techniques and experimental design to better understand DOM. This book offers select case studies focusing on the advanced characterization of DOM in different environments and with respect to different processes. It results from the conclusion of a symposium that E. M. Thurman and I had organized for the 245th meeting of the American Chemical Society, which was held on April 7-11, 2013 in New Orleans, Louisiana.

Download or read book Characterization of Dissolved Organic Matter in Water Using Fourier Transform Infrared Spectroscopy and X ray Photoelectron Spectroscopy written by Shichen Zhang and published by . This book was released on 2015 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissolved organic matter (DOM) from several freshwater sources (Hinkson Creek upstream and downstream of the City of Columbia, Missouri River, landfill leachate, and wastewater treatment plant (WWTP)) was characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The goal was to identify major chemical compound classes, such as carboxylic acid, amide, ester, and aliphatic and aromatic characteristics in water samples from different sources. Results showed that samples from the city landfills contained the highest concentration of aromatic and protein-like compounds, while samples from WWTP contained more acids and hydrophilic fraction. It appeared that for freshwaters, the DOM inputs from the surroundings had a significant effect on the DOM chemical composition. The study demonstrated that coupling FTIR with XPS analyses could provide insights into the physicochemical and biogeochemical characteristics of DOM in different aquatic systems, as well as the characteristics of the environments from which the DOMs were derived.

Download or read book Characterization and Remediation of Dissolved Organic Matter in Produced Oilfield Waters written by Xiaojing Wang and published by . This book was released on 2011 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissolved Organic Matter (DOM) has been studied intensively in many water sources such as lakes and seas due to its recalcitrance, its reactivity with other pollutants in water, its role in global carbon cycling, and the fact that DOM is a precursor of carcinogenic disinfection byproducts. The composition of DOM is complex and contains thousands of chemicals. Compared to DOM in other types of water bodies (fresh and sea waters), little research has been conducted on DOM in produced oilfield waters, and its detailed composition remains largely unknown. This works aims to understand DOM in oilfield waters through a thorough chemical characterization and examination on mechanisms for its removal through both biotic and abiotic methods, including: (1) Solid Phase Extraction of DOM; (2) FTIR and high resolution mass characterization of DOM; (3) remediation of DOM through photodegradation, clay adsorption, chemical flocculation, biodegradation, and volatilization.
Download or read book Characterization of Natural Organic Matter in Drinking Water written by Jean-Phillipe Croue and published by American Water Works Association. This book was released on 2000 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research reported on here sought to characterize natural organic matter (NOM) in dilute solutions and to isolate it without altering its properties, so that the effect of NOM in drinking water may be considered. Several NOM isolation methods were evaluated, including evaporation, reverse osmosis, nanofiltration, and adsorption. The effects of such isolation procedures on NOM's chemical composition and reactivity were considered. Based on these studies, the report presents conclusions regarding the feasibility and adequacy of in situ and ex situ techniques. Croue is affiliated with Laboratoire de Chimie de l'Eau de l'Environment, Universite de Poiters. Annotation copyrighted by Book News, Inc., Portland, OR.
Download or read book Dissolved Organic Matter DOM written by Oleg S. Pokrovsky and published by Nova Science Publishers. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissolved Organic Matter (DOM) is a major factor controlling global biogeochemical cycles of carbon, macro- and micronutrients and toxic metals. It plays a pivotal role both in mobilisation (chemical weathering), transport (organic complexes and colloids), biological uptake and deposition (microbial and photo-degradation) of a number of essential macro- (C, N, P) and micro- (Fe, Zn, Mn, Ni, Cu Co) nutrients. The interest of scientists to DOM is rapidly increasing. Between 1950 and 2017, more than 30,000 scientific papers on DOM were published (Web of Science® All Database Search); however, more than half of them were produced over the past nine years and over the last two and a half years, more than 5,400 papers were published. Such attention to DOM is clearly motivated by a combination of global climate change issues and the main role of DOM in CO2 exchange between the atmosphere and the surface waters. Despite such a large range of scientific problems concerning DOM properties, origins, and applications, there is a very strong geographical bias in terms of the amount of research devoted to various geographical regions of the world. The majority of information concerns temperate zones and boreal regions of Scandinavia and Northern America, with very little information available on Siberia and Russia. Thus, among the less than 30,000 scientific articles devoted to various aspects of DOM since 1950, only 150-200 of them are devoted to DOM in Russia or Siberia. This book is essentially oriented towards filling these gaps of our knowledge. Among thirteen chapters, eleven of them are devoted to various aspects of DOM in Russia and Siberia. Another important and still poorly characterised aspect of natural DOM is its colloidal status: four chapters of this book deal with the colloidal speciation of DOM in rivers and lakes. Given the breadth of physico-chemical, geochemical, biological, and geographical aspects of DOM covered in this book, it will be useful for a large audience of environmental scientists, limnologists, physico-chemists, soil and landscape scientists and biogeochemists.
