Download or read book Ion Exchange in Analytical Chemistry written by William Rieman and published by Elsevier. This book was released on 2013-10-22 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical Chemistry, Volume 38: Ion Exchange in Analytical Chemistry provides a broad survey of the important role that ion exchange can and should play in chemical analysis. This book focuses on the plate-equilibrium theory of chromatography, which is less difficult theoretically than the mass-transfer theory. Organized into 11 chapters, this volume begins with an overview of the earliest recorded application of ion exchange. This text then examines how high temperature affects ion-exchange resins. Other chapters consider the exchange of ions between a solid ion-exchanging material and a solution, which is a typically reversible reaction. This book describes as well the relatively simple separations and other applications of ion exchange to analytical chemistry. The final chapter deals with the interesting nature of the metal complexes formed within the exchanger and describe the use of ion-exchange distribution studies to determine the stability and nature of complexes existing in the solution. This book is a valuable resource for analytical chemists.

Download or read book Toxicological Profile for Chromium written by U.s. Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-01-22 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the toxic substances each profile describes. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The profiles focus on health and toxicologic information; therefore, each toxicological profile begins with a public health statement that describes, in nontechnical language, a substance's relevant toxicological properties. Following the public health statement is information concerning levels of significant human exposure and, where known, significant health effects. A health effects summary describes the adequacy of information to determine a substance's health effects. ATSDR identifies data needs that are significant to protection of public health. Each profile: (A) Examines, summarizes, and interprets available toxicologic information and epidemiologic evaluations on a toxic substance to ascertain the levels of significant human exposure for the substance and the associated acute, subacute, and chronic health effects; (B) Determines whether adequate information on the health effects of each substance is available or being developed to determine levels of exposure that present a significant risk to human health of acute, subacute, and chronic health effects; and (C) Where appropriate, identifies toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.

Available in PDF, EPUB and Kindle. Book excerpt: Chromium nutritional supplements are the second best selling mineral supplements after calcium as chromium is found in pills, sports drinks, chewing gums, smoothies, and numerous other products. Chromium has been promoted to promote weight loss and muscle development and most recently to be available to treat the symptoms of type 2 diabetes and related conditions. The aim of The Nutritional Biochemistry of Chromium(III) is to examine the four most controversial areas of chromium nutrition and biochemistry: - is chromium an essential element for humans and are chromium nutritional supplements of value? - what biochemical role, if any, does chromium play in the body - can large doses of chromium(III) be used to treat symptoms of type 2 diabetes, cardiovascular disease, and related medical conditions - is the use of chromium(III) supplements a health concern. Scientific experts, who are recognized leaders in the field, weigh in with their opinions on both sides of these issues in this book.A background review of the field from 1955-1995 by Vincent opens the book and concludes with a summary by Dr. Forrest Nielsen, Center Director of the USDA's Grand Forks Human Nutrition Research Center concludes the book.* Point-counterpoint format, providing both sides of major issues* Complete coverage of current issues, including nutrition, health, biochemical role and toxicology* Authors are recognised experts and leaders in this field

Download or read book Binding Transport and Storage of Metal Ions in Biological Cells written by Wolfgang Maret and published by Royal Society of Chemistry. This book was released on 2014-07-09 with total page 990 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.

Download or read book Industrial Biotechnology written by Indu Shekhar Thakur and published by I. K. International Pvt Ltd. This book was released on 2013-12-30 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last five decades have witnessed a tremendous upsurge in the amount of xenobiotic compounds in the environment by industrial activities, some of them being highly toxic, recalcitrant with high bio-accumulating and bio-magnification properties. Whilst biotechnology is the development of products or processes using plants, animals or micro-organisms, ''Environmental Biotechnology'' is the multidisciplinary integration of sciences and engineering to utilise the huge biochemical potential of microorganisms and plants for the sustenance of resources. Recent advances in biotechnology have driven forward the harnessing of micro-organisms and plants to help and protect our fragile environment and formation of ecofriendly products. The aim of this book is to determine the processes and utilization of raw materials in the industries, formation and release of pollutants (air, water and soil) in the environment, effect and impact of the pollutants on biotic and abiotic components of the environment and finally identifying the physical, chemical, biological and alternating methods for treatment of pollutants in the industrial effluents. Efforts have also been made to identify the methods for bioconversion and recovery of products from the effluents by biotechnological methods.
Download or read book Low Level Hexavalent Chromium Treatment Options written by Philip Brandhuber and published by American Water Works Association. This book was released on 2005-07-31 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 1999, the California Office of Environmental Health Hazard Assessment issued a Public Health Goal (PHG) for total chromium of 2.5 μg/L. The PHG, based on a 10^6 risk level for 0.2 μg/L hexavalent chromium [Cr(VI)], was 40 times less than the USEPA's contaminant MCL of 100 μg/L for total chromium [Cr(III) ] Cr(VI)]. The success of the movie Erin Brockovich, which popularized a groundwater chromium pollution lawsuit in Hinkley, California, sensitized the public to the health hazards of chromium in drinking water. In 2001, the California state legislature passed a bill requiring the California Department of Health Services to adopt an MCL for Cr(VI). All of these actions must be viewed from the perspective that, at the time, no technology had been demonstrated to be effective at treating chromium to concentrations consistent with the total chromium PHG or the Cr(VI) 10^6 risk level of 0.2 μg/L. The purpose of this report was to present the results of this partnership study, which included an analysis of chromium occurrence and co-occurrence, an evaluation of Cr(VI) removal technologies, and an examination of chromium oxidation and reduction chemistry. This study investigated nearly all of the potential methods of controlling Cr(VI) either through the use of technologies that remove Cr(VI) directly (adsorption, anion exchange, membrane filtration) or those that remove the reduced form of chromium, Cr(III) (precipitation with membranes or coagulation and precipitation with conventional or membrane filters). These technologies were investigated using laboratory-scale testing methods, including batch isotherm tests, bench membrane systems, flow-through mini-columns, and jar testing techniques. For most technologies, controlled water matrices were used to screen performance. Selected technologies were further assessed using natural groundwater matrices from the Los Angeles Department of Water and Power and the Glendale Water and Power groundwater facilities.
