Book Description
At the beginning of the twenty-firstst century, separation processes presented a comprehensive application of the major operations performed by various industries, such as chemical, food, environmental, and biotechnology. Sorption, one of the preferred separation processes because of its effectiveness at different interfaces, has caught the attention of many scientists. This book is aimed at gaining a general knowledge of sorption and a number of extremely important applications, as well as recognizing its functions and paramount importance in chemical and biochemical plants, including environmental treatment. Moreover, progress in the phenomenon is highlighted in this book. To help provide instruction in the important sorption processes, we have chosen authors who have extensive industrial and academic experience in closing the gap between theory and practice. Crucial progress in the theoretical information section of sorption has been achieved, mainly through the development of new techniques that examine the usage of various sorbents, including nanomaterials for the removal of various pollutants. We have subdivided the book into several sections, one of which is focused on applications of the sorption process, which presents real results of the recent studies and gives a source of up-to-date literature. The relationship between the sorption process and isotherm and kinetics modeling is analyzed in another chapter. This book will be a reference book for those who are interested in sorption techniques from various industries.

Book Description
In this day and age, the chemical process engineer strives to make products at a lower cost, with less pollution, while using a variety of raw materials. When a new product or process is found to be successful, more plants are built either by retrofit or existing similar plants, or by construction of large plants. Engineers involved in the scaling of new plants will need a solid understanding of the issues involved in multiple reactions, which can happen in a series, in parallel, and can be reversible. Computer software can be used provide detailed treatments of these reactions and readers of Multiple Reactions Galore will learn how to treat intermediate products during a complex reaction scheme. This two-volume set discusses the engineering design issues involved when multiple reactions occur in the considered process. Design issues such as product distribution, economic analysis and profitability as well as the sensitivity of important quantities such as yield, selectivity to rate constant ratios, will be presented in detail. The author explains how to use Excel spreadsheets to seek numerical solutions when closed form analytical solutions are not possible. The author also explores the importance of by-product and by-product yield, which is often overlooked in traditional reaction engineering textbooks.

Book Description
Reports the current thinking on the role that adsorption may play in the rate and extent of an organic compound's degradation in the soil. Among the topics of the 14 papers are diazinon degradation and dissipation in the root zone, the reductive dechlorination of hexachlorobenzene in wetland soils, and the utility of sorption and degradation parameters from the literature for site-specific pesticide impact assessments.

Book Description
Environmental Soil Chemistry, Third Edition provides an up-to-date overview of the interdisciplinary field of environmental soil chemistry. This classic text covers the fundamental principles of soil chemistry, including the inorganic and organic components of soil, soil porewater chemistry, interfacial chemical reactions between solids and dissolved ions/molecules, ion exchange, and the kinetics of the soil chemical process, such as sorption and redox. Soil acidity and salinity are also discussed. This fully updated third edition places particular emphasis on environmental reactions between clay minerals, metal oxides, and soil organic matter with heavy metals, pesticides, and industrial contaminants. This text provides the latest technological advances representing the cutting edge of the science. Completely updated throughout with new content and updated full color figures, the third edition contains expanded information on soil minerals and an increased emphasis on the coupling between chemical and biological reactions, mechanisms, and processes. This third edition provides upper-level undergraduate and graduate students in soil science with sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns. The book offers a competitive advantage for those students looking to incorporate novel, advanced tools into their research. Includes problem sets in each chapter for enhanced learning and comprehension Emphasizes soil organic carbon reactions with clay minerals and metal oxides, including examples from advanced spectromicroscopic techniques Features revised content highlighting the role of soils in environmental and ecosystem services Presents new material on advances in surface complexation modeling Delivers concise summaries of research using state-of-the art techniques Highlights advances in understanding reactions at mineral-water interfaces, including adsorption, dissolution, and surface precipitation Offers a new online course supplement for instructors

Book Description
Modeling Processes and Their Interactions in Cropping Systems A complete discussion of soil-plant-climate-management processes In Modeling Processes and Their Interactions in Cropping Systems: Challenges for the 21st Century, a team of distinguished researchers delivers a comprehensive and up-to-date scientific textbook devoted to teaching the modeling of soil-plant-climate-management processes at the upper undergraduate and graduate levels. The book emphasizes the new opportunities and paradigms available to modern lab and field researchers and aims to improve their understanding and quantification of individual processes and their interactions. The book helps readers quantify field research results in terms of the fundamental theory and concepts broadly generalizable beyond specific sites, as well as predict experimental results from knowledge of the fundamental factors that determine the environment and plant growth in different climates. Readers will also discover: An introduction to water and chemical transport in the soil matrix and macropores Explorations of heat transport, water balance, snowpack, and soil freezing Discussions of merging machine learning with APSIM models to improve the evaluation of the impact of climate extremes on wheat yields in Australia Examinations of the quantification and modeling of management effects on soil properties, including discussions of tillage, reconsolidation, crop residues, and crop management The book will be essential reading for anyone interested in the 2030 breakthroughs in agriculture identified by the National Academies of Sciences, Engineering, and Medicine.

Book Description
An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the atmosphere above, the biosphere within, and the geology below. It acts as an anchor for roots, a purveyor of water and nutrients, a residence for a vast community of microorganisms and animals, a sanitizer of the environment, and a source of raw materials for co
