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.

This study aimed to investigate and to quantify the impact of sorption processes on perceived air quality using sensory panels as the measuring device. The experiments were performed in four similar, adjacent, unfurnished offices. Samples of carpet, painted gypsum board, virgin gypsum board, linoleum and Semia were tested individually and as a combination of two materials. To investigate the interaction between the pollutants emitted from the test building materials and the actual room surfaces, the air polluted by two different building materials was mixed in a separate room without the presence of the building materials. Each experiment lasted between one week (adsorption stage only) to 10 days (adsorption and desorption stages). Untrained panels assessed the air quality at specific time intervals after moving the materials into or out of the rooms, depending on the design of each experiment. The results indicated that sorption affects the perceived air quality significantly. For all performed experiments, the presence of an additional room surface (samples of painted gypsum board) together with samples of carpet or linoleum improved the perceived air quality in that room and in comparison to the air in the room with carpet alone or painted gypsum board alone. The improvement was consistent despite the different kind of building materials used in the experiments, the different panels that performed the sensory assessments and the different environmental conditions for the different experiments. Moreover, adsorption/desorption coefficients for the room surfaces and the painted gypsum board were calculated assuming a Langmuir type of adsorption and when the pollution source was either carpet or linoleum. As anticipated the linear Langmuir model appeared to be suitable for the painted gypsum board and the room surfaces (flat smooth surfaces). In this work, based on sensory data, it was possible to get reasonable values for sorption parameters for painted gypsum board and the room surfaces presumably because the chemicals emitted from the carpet or linoleum used in the experiments were relatively similar in terms of their sorption parameters. The results demonstrated that sensory assessments could be used to derive sorption parameters for common indoor materials interacting with common indoors pollution sources.

This is the second volume on adsorption using green adsorbents and is written by international contributors who are the leading experts in the adsorption field. Together with the first volume they show a typical selection of green materials used in wastewater treatment, with emphasis on industrial effluents. This second volume focuses on innovative materials. It presents hemp-based materials for metal removal, and the use of leaves for metal removal. It describes the biosorption of metals and metalloids on various materials and discusses the recent advances in cellulose-based adsorbents used in environmental purposes. Furthermore, activated carbons from food wastes, aerogels and bones, and municipal solid waste biochar as efficient materials for pollutant removal, respectively are reviewed as well as biosorption of dyes onto microbial biosorbents and the use of mushroom biomass to remove pollutants are looked at. The volume also includes detailed review of green adsorbents for removal of antibiotics, pesticides and endocrine disruptors and the use of pillared interlayered clays as innovative materials for pollutant removal. Finally, the use of green adsorbents for radioactive pollutant removal from natural water is discussed. The audience for this book includes students, environmentalists, engineers, water scientists, civil and industrial personnel who wish to specialize in adsorption technology. Academically, this book will be of use to students in chemical and environmental engineering who wish to learn about adsorption and its fundamentals. It has also been compiled for practicing engineers who wish to know about recent developments on adsorbent materials in order to promote further research toward improving and developing newer adsorbents and processes for the efficient removal of pollutants from industrial effluents. It is hoped that the book will serve as a readable and useful presentation not only for undergraduate and postgraduate students but also for the water scientists and engineers and as a convenient reference handbook in the form of numerous recent examples and appended information.

The soil is the medium through which pollutants originating from human activities, both in agriculture and industry, move from the land surfaces to groundwater. Polluting substances are subject to complex physical, chemical and biological transformations during their movement through the soil. Their displacement depends on the transport properties of the water-air-soil system and on the molecular properties of the pollutants. Prediction of soil pollution and restoration of polluted soils requires an under standing of the processes controlling the fate of pollutants in the soil medium and of the dynamics of the contaminants in the un saturated zone. Our book was conceived· as a basic overview of the processes governing the behavior of pollutants as affected by soil constituents and environmental factors. It was written for the use of specialists working on soil and unsaturated zone pollution and restoration, as well as for graduate students starting research in this field. Since many specialists working on soil restoration lack a back ground in soil science or a knowledge of the properties of soil pollutants, we have included this information which forms the first part of the book. In the second part, we discuss the partitioning of pollutants between the aqueous, solid and gaseous phase of the soil medium. The retention, transformation and transport of pollutants in the soils form the third section.
