Available in PDF, EPUB and Kindle. Book excerpt: Arsenic(As), one of most toxic contaminants found in water, is well known to have adverse effects on human health, such as skin cancer. The consumption of arsenic contaminated water has led to human health crises in many countries such as Bangladesh, China and even the western USA. The new EPA standard for arsenic in drinking water is 10 [Mu]g/L, and many smaller drinking water treatment plants are in need of additional treatment to achieve this. Recently, many researchers have being trying to find inexpensive and disposable adsorbents for many small-scale water systems or individual ground wells, which are used in most arsenic endemic areas. The adsorption of As(V) using iron and aluminum oxides has been considered as one of the most effective small-scale techniques for arsenic removal. Two types of nonporous adsorbents were used in this dissertation: iron oxide (Fe2O3) from a byproduct of the steel industry, and aluminum oxide (AI2O3) as a chemical powder. Due to their fast adsorption of As(V) anions and low cost, Fe2O3 and AI2O3 were found to be good and inexpensive adsorbents in lowering As(V) initial concentration in drinking water at a lower pH (

This book was released on 2015 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second part of the research, Sol-gel derived activated alumina, supercritical carbon dioxide dried sol-gel derived activated alumina, and iron-aluminium hydrous oxides were synthesized to study the adsorption equilibrium and kinetics of arsenic removal. The main application of this study is to remove arsenic at very low concentrations from drinking water. The adsorbents were characterized using scanning electron microscope (SEM) and nitrogen adsorption for their surface and pore texture properties. The iron-aluminium hydrous oxide adsorbent was independent of the initial pH of the solution for arsenic removal. Adsorption isotherm arsenic onto sol-gel derived activated alumina is explained by the Freundlich adsorption model and the Langmuir adsorption model best explains the adsorption isotherm of arsenic onto supercritical CO2 dried sol-gel derived activated alumina and iron-aluminium hydrous oxides. Supercritical CO2 dried sol-gel derived activated alumina showed the highest adsorption capacity of 8.99 mg/g. A pseudo-second order model is used to explain adsorption reaction kinetics of arsenic onto the adsorbents and the pseudo-second order model fits the experimental data very well with a R2 value greater than 0.99.

Available in PDF, EPUB and Kindle. Book excerpt: Considerable recent research has focused on the topic of chemical speciation in the environment. It is increasingly realised that the distribution, mobility and biological availability of chemical elements depend not simply on their concentrations but, critically, on the forms in which they occur in natural systems. Continuing developments in analytical chemistry have made speciation practicable even where analytes are present at trace levels (as is often the case in natural samples). In the second edition of this book, the expertise of scientists involved in chemical speciation in various fields have been brought together to provide an overview of the current status of speciation science and indicate how the field may develop in the future.

Download or read book The Environmental Chemistry of Aluminum written by Garrison Sposito and published by CRC Press. This book was released on 2020-04-08 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Chemistry of Aluminum provides a comprehensive, fundamental account of the aqueous chemistry of aluminum within an environmental context. An excellent reference for environmental chemists and scientific administrators of environmental programs, this book contains material reflecting the many recent changes in this rapidly developing discipline. The first three chapters discuss the most fundamental aspects of aluminum chemistry: its quantitation in soils and natural waters, including speciation measurements, and its stable chemical forms, both as a dissolved solute and in a solid phase. These chapters emphasize both critical assessments of and definitive recommendations for laboratory methodologies and measured thermodynamic properties relating to aluminum chemistry. The next four chapters in The Environmental Chemistry of Aluminum build on this foundation to provide details of the polymeric chemistry of aluminum: its polynuclear and colloidal hydrolytic species in aqueous solution, its complexes with natural organic ligands, including humic substances, and its role as an adsorptive and adsorbent in surface reactions. These chapters are grounded in experimental results rather than conceptual modeling. The final three chapters describe the chemistry of aluminum in soils, waters, and watersheds. These chapters illustrate the problems of spatial and temporal variability, metastability, and scale that continue to make aluminum geochemistry one of the great challenges in modern environmental science.

Download or read book Biomarkers and Human Biomonitoring written by Lisbeth Knudsen and published by Royal Society of Chemistry. This book was released on 2011-10-19 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human biomonitoring has developed from a research tool in occupational and environmental health to identify and quantify exposures to harmful substances in urine and blood. The analytical methods for detection of substances in biological media have considerably improved with smaller detection limits and more precise and specific measurements. Human biomonitoring is a valuable tool in exposure estimation of selected populations and currently used in surveillance programs all over the world. This two volume set provides an overview of current available biomarkers and human biomonitoring programs in environmental health, which is timely given the present debate on adverse health effects from environmental exposures. The books decribe both previous and ongoing studies as well as the newer biomarkers of exposure and effects. Volume one describes current human biomonitoring programs in Germany, Romania, France, Canada, India and Belgium, providing convincing evidence of a global decline in human exposures to lead and increasing concern from exposure to endocrine disruptors and the genotoxic compound. Biomarkers of specific exposures to a wide range of widely used everyday compounds such as phthalates, PFCs, bisphenol A, brominated flame retardants, PAHs, dioxins, mercury and arsenic are also discussed. Volume two decribes human biomonitoing of exposures to environmental tobacco smoke, mycotoxins, physiological stress, hormone activity, oxidative stress and ionizing radiation, as well as effect biomarkers of hemoglobin adducts, germ cells, micronuclei and individual susceptability. The books will be essential reading for toxicologists, environmental scientists and all those working in the safety and risk assessment of chemicals.

This book was released on 2019-04-11 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural attenuation has become an effective and low-cost alternative to more expensive engineered remediation. This new edition updates the principles and fundamentals of natural attenuation of contaminants with a broader view of the field. It includes new methods for evaluating natural attenuation mechanisms and microbial activity at the lab and field scales. Case studies, actual treatments and protocols, theoretical processes, case studies, numerical models, and legal aspects in the natural attenuation of organic and inorganic contaminants are examined. Challenges and future directions for the implementation of natural attenuation and enhanced remediation techniques are also considered.
