Download or read book Colloids in the Aquatic Environment written by Th. F. Tadros and published by Elsevier. This book was released on 2013-10-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloids in the Aquatic Environment covers the proceedings of the International Symposium by the same title, held at the University College London on September 7-9, 1992, organized by the SCI Colloid and Surface Chemistry Group. This book is divided into 20 chapters and begins with an introduction to the fundamentals of surface structure and reactivity. The succeeding chapters deal with molecular mass determination of humic substances from natural waters, the biospecific mechanism of double layer formation, the dynamics of colloid deposition in porous media, and the evaluation of surface area and size distributions of soil particles. These topics are followed by discussions of the transport and capture of colloids; colloidal stability of natural organic matter; the hydrolytic precipitation and modeling ion binding by humic acids; and the thermodynamic aspects and photoelectrophoresis of colloids. Other chapters explore the colloidal transfer in several aquatic environments. The final chapters consider the mechanism of colloid detachment, speciation, partitioning, and stability. These chapters also look into a hybrid equilibrium model of solute transport in porous media in the presence of colloids. This book will be of great value to civil and environmental engineers.
Download or read book Manipulation of Groundwater Colloids for Environmental Restoration written by John McCarthy and published by CRC Press. This book was released on 1993-01-04 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This valuable resource discusses several strategies of manipulating colloids for environmental restoration, identifies advantages and disadvantages of each strategy, and considers obstacles limiting the application of each strategy. Approaches evaluated include the following: Chemical modification of subsurface systems to mobilize or deposit colloids in situ Altering the mobility of microorganisms to improve delivery of microbes for bioremediation Manipulating colloids or biocolloids (bacteria) to change aquifer permeability to either enhance bioremediation or create in situ barriers Introducing modified colloids, surfactants, and emulsions to control colloid mobility or to increase recovery of sorbed contaminants by pump and treat methods Manipulation of Groundwater Colloids for Environmental Restoration also contains short, focused research reports on specific studies relevant to the various approaches under consideration. Subjects covered range from mobility of organic macromolecules by controlled field injection experiments to new techniques that investigate surface chemistry and aggregation of inorganic colloids. Other topics discussed include the depositional behavior and transport of biocolloids in porous media, surfactants as modifiers of surface binding sites on colloids, and genetic engineering of microorganisms to serve as contaminant-scavenging biocolloids. Manipulation of Groundwater Colloids for Environmental Restoration is an excellent resource for research scientists in hydrology, chemistry, and microbiology; environmental consultants; regulators; environmental engineers; bioremediation microbiologists; and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Often too little attention is given to the sampling before and after actual instrumental measurement. This leads to errors, despite increasingly sensitive analytical systems. This is one of the first books to pay proper attention to representative sampling. It offers an overview of the most common techniques used today for taking environmental samples. The techniques are clearly presented, yield accurate and reproducible results and can be used to sample - air - water - soils and sediments - plants and animals. A comprehensive handbook, this volume provides an excellent starting point for researchers in the rapidly expanding field of environmental analysis.
