Category :

Pages : 188

Book Description
The range of topics addressed in this publication is considerable from phenols and nitro substituted toxic phenols to low cost clay. The study examines the effectiveness of nearly inexpensive sorbent clay in removing phenols from wastewater by sorption. The influences of various factors, such as particle size, pH, concentration and temperature on the sorption capacity have been studied. This study showed that clay could be used as an efficient sorbent material for the sorption of phenols from aqueous solutions. Langmuir isotherm and Kinetics adsorption constants were calculated and it is seen that the sorption data for phenols onto clay fitted well in this model. The study is important for designing batch reactor treatment plant for phenolic effluents where continuous removal can be achieved on a large scale. This publication represents an advanced textbook for graduate students and as well as offering to research workers who are working in the field of adsorption. The publication will appeal to workers, researchers and will act as a vital resource for chemists, environmentalists, sorption scientists, post-graduate students, doctoral and post-doctoral fellows.

Sediments and Toxic Substances

Sediments and Toxic Substances PDF Author: Wolfgang Calmano
Publisher: Springer Science & Business Media
ISBN: 364279890X
Category : Science
Languages : en
Pages : 335

Book Description
In modern sediment research on contaminants five aspects are discussed which, in an overlapping succession, also reflect develop ment of knowledge on particle-associated pollutants during the past twenty-five years: (1) identification of sources and their distribution; (2) evaluation of solid/solution relations; (3) study of transfer mecha nisms to biological systems; (4) assessment of environment impact; and (5) selection and further development of remedial measures, in par ticular, of dredged materials. Scientific research and practical develop ment are still expanding in all these individual aspects. Similar to other waste materials, management of contaminated sed iments requires a holistic approach. This means that assessment of biogeochemical reactions, interfacial processes and transfer mecha nisms as well as the prognosis of long-term borderline conditions, in particular of capacity-controlling properties, should be an integrated part of the wider management scheme, i.e., the analytical and experi mental parameters should always be related to potential remediation options for a specific sediment problem. The underlying coordinated project, which was funded by the German Federal Ministry for Science and Technology (now the Federal Ministry for Education, Science, Research and Technology) provided excellent opportunities for multidisciplinary effort, bringing together biologists, chemists, engineers, geologists and other researchers. During its active phase, the group attracted much interest nationally and internationally. The group members highly appreciate the manifold contacts and invitations during the past five years.

Environmental Water

Environmental Water PDF Author: V.K. Gupta

Languages : en
Pages : 232

Book Description
The world is facing a drinking water crisis. Besides continuous population growth, uneven distribution of water resources and periodic droughts have forced scientists to search for new and effective water treatment, remediation and recycling technologies. Therefore, there is a great need for the development of suitable, inexpensive and rapid wastewater treatment and reuse or conservation methods. This title discusses different types of wastewater treatment, remediation and recycling techniques, like adsorption, membrane filtration and reverse osmosis. It also provides guidance for the selection of the appropriate technologies or their combinations for specific applications so that one can select the exact and accurate technology without any problem. The book comprises detailed discussion on the application of various technologies for water treatment, remediation and recycling technologies and provides an update on the development in water treatment, detailed analysis of their features and economic analysis, bridging the current existing information gap. Each chapter is also documented by references and updated citations. Provides guidance for the selection of the appropriate technologies to industrialists and government authorities for the selection of exact, inexpensive technologies for specific problem solving Discusses the developments of inexpensive and rapid wastewater treatment, remediation and recycling Gives information on the application of analytical techniques, such as GC, LC, IR, and XRF for analysing and measuring water Provides an updated development in water treatment technologies, detailed analysis of their features and economic analysis, enabling to choose a problem-specific solution Completely updates the current knowledge in this field, bridging the current existing information gap

Toxic Organic Chemicals in Porous Media

Toxic Organic Chemicals in Porous Media PDF Author: Zev Gerstl
Publisher: Springer Science & Business Media
ISBN: 3642744680
Category : Science
Languages : en
Pages : 343

Book Description
In March, 1983 a workshop on Pollutants in Porous Media was hosted by the Institute of Soils and Water of the Agricultural Research Organi zation in Bet Dagan, Israel. At this workshop, the unsaturated zone be tween the soil surface and groundwater was the focal point of discus sions for scientists from various disciplines such as soil chemists, physicists, biologists and environmental engineers. Since then, the prob lem of soil and water pollution has only worsened as more and more cases of pollution caused by human activities including agriculture and industry have been revealed. A great deal of work has been carried out by environmental scientists since 1983 in elucidating the behavior of the many classes of pollutants and the complex physical, chemical, and bio logical transformations which they undergo as they move through the soil to the vadose zone and, in many cases, the groundwater. In light of this, it was felt that another meeting of specialists from the many disciplines which deal with this subject was necessary and so a Second International Workshop on the Behavior of Pollutants in Porous Media, sponsored by IUPAC (the International Union of Pure and Applied Chemistry) and IAHS (the International Association of Hydrological Sciences), was organized and held in the Institute of Soils and Water of the Agricultural Research Organization in Bet Dagan, Israel during 1987. June, The present volume is a selection of the talks presented at this second workshop and deals only with toxic organic chemicals in porous media.
