Available in PDF, EPUB and Kindle. Book excerpt: The mechanism for the detection of copper by ion selective electrodes in seawater has been examined. Contrary to common perception, the direct detection of copper with ion selective electrodes is unlikely to be possible due to the low levels of uncomplexed copper present. Instead, it is proposed that the ion selective electrodes measure the activity of naturally-occurring binding ligands for copper and thereby provide an indirect determination of uncomplexed copper, which is the species most likely to be toxic to organisms. A potentially automated system is described to measure the complexing ability of the seawater system for copper and other metals. This system can allow the determination of excess binding capability for the water system and thereby predict if a water body can absorb extra toxic metals.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major source of trace metal contamination in the marine environment is the copper containing anti-fouling paints on ship halls. This research examines the potential of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (Bathocuproine=BCP) embedded in the polymer, Nafion 117, for use as a reliable chemical for developing a sensor capable of measuring copper(I) in seawater. The sensor must have: (1) parts per billion (ppb) detection limits; (2) capable of operation in marine environments; (3) the ability to detect copper(I) within 17% of measurements made with the Standard Method BCS procedure. The use of the polymer with Bathocuproine (BCP) allows for a rapid electronic measurement. This electronic measurement uses optical fibers running from a small spectrophotometer to either a flow through or a submersible device containing the BCP impregnated polymer. Response times for the devices depend on the size of the membrane used and the flow rate. The flow cell takes eight minutes to reach a peak optical density while the submersible probe takes one minute. Nafion 117 polymer impregnated with Bathocuproine (BCP) is a rapid method used for detecting copper(I) released into the marine environment.

Book Synopsis Methods of Seawater Analysis by : Klaus Grasshoff
Download or read book Methods of Seawater Analysis written by Klaus Grasshoff and published by John Wiley & Sons. This book was released on 2009-07-30 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.

Book Synopsis Trace Metal Analysis and Speciation by : I.S. Krull
Download or read book Trace Metal Analysis and Speciation written by I.S. Krull and published by Elsevier. This book was released on 1991-10-08 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to describe the most recent advances in areas of analytical chemistry that relate to the trace determination of metals and inorganics, as well as their distribution and forms (species) present, sample dependent. Analytical approaches are described that encompass a number of separation methods, such as gas and high performance liquid chromatography, interfaced with selective and sensitive detection methods that become unique for metal species/forms present in various samples. Hyphenated techniques are emphasized, such as interfacing HPLC with plasma induced emission spectroscopy, electrochemistry, post-column reaction chemistry, etc. Each chapter describes the latest instrumental and methodology advances that utilize some form of chromatography together with element-specific detection or mass spectrometry to provide absolute identification of the specific species of a metal present in various samples. The book will be of value to those concerned with the determination of trace levels of individual metal species present or suspected present in any given sample and to those involved in trace metal toxicology, metabolism of metal-containing drugs or chemicals, environmental exposures to metals and chemical speciation of real world samples. Government regulatory laboratories striving to detect and determine absolute levels of a metal species in any regulated sample will be interested in this volume, as will academic institutes involved in environmental toxicology, environmental chemistry, metal-DNA/protein interactions and researchers working with metal species.
