This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2006 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tetrachloroethylene (PCE) is a volatile chlorinated hydrocarbon commonly used as a solvent in metal degreasing and dry cleaning industries. A high concentration of PCE can be evidently found in the surface water and groundwater. This research aimed to investigate a novel separation technique called aqueous surfactant two-phase system (ASTP) using mixtures of cationic and anionic surfactants to preconcentrate and extract PCE from wastewater. The ASTP system has a unique characteristic where an aqueous surfactant solution can separate into two micellar phases. One is the surfactant-rich phase containing most of surfactant aggregates and solubilized pollutants; and the other is the surfactant-dilute phase which contains only small amount of surfactants and pollutants as treated water. The preliminary study on surfactant system selection reveals that the suitable cationic and anionic surfactants composition forming a stable ASTP system is DTAB:DOWFAX 8390 at molar ratio of 2:1. The total surfactant concentration was investigated in the range of 30 to 110 mM and found that the total surfactant concentration of 70 mM is the most suitable working condition in which the fraction of PCE removal is 91.4% or only 8.6 ppm of PCE remains in the surfactant-dilute phase from the original PCE concentration of 100 ppm. Moreover, an addition of lipophilic linkers (long straight chain alcohols; n-octanol, n-dodecanol, and n-hexadecanol) and nonionic surfactants (POE surfactants; TX-114 and TX-100) was found to enhance the PCE solubilization of this ASTP system. An addition of small amount of nonionic surfactant (2 mM) can greatly increase the fraction of PCE removal to about 96 % or only 4 ppm of PCE is left in the surfactant-dilute phase. Among three alcohols studied here, n-dodecanol shows the greatest ability to enhance the PCE solubilization, in which up to 98% of PCE is extracted within single stage with an addition of 0.1 mM dodecanol only. However, the concentrations of nonionic surfactants and alcohols added do not have significant effect onto the PCE removal efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Featuring the theme, From Sources to Solution, this book is based on the research papers presented during the International Conference on Environmental Forensics 2013. It covers multi-disciplinary areas of environmental forensics featuring major themes: characterization, assessment, and monitoring; new approach, rapid assessment, and analytical techniques; pollution control technology; environmental health risk assessment; and policy, governance and management. It present information for researchers from the science and social sciences disciplines and contribute to the advancement of Environmental Forensics. It also aims at evaluating the environmental damages as the result of indiscriminating discharge of toxic environmental pollutants.
Book Synopsis Contaminants in the Subsurface by : National Research Council
Download or read book Contaminants in the Subsurface written by National Research Council and published by National Academies Press. This book was released on 2005-04-23 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.
