Download or read book Advances in Analytical Features of Electrochemical Methods for the Analysis of Complicated Real Samples written by Masoud Fouladgar and published by Frontiers Media SA. This book was released on 2024-08-23 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the challenges in Analytical chemistry is the analysis of complicated real samples. Analytical methods commonly suffer from interference and several limitations for the analysis of these samples. These limitations may be due to inherent problems of method or the nature of the sample matrix. Although electrochemical methods have several advantages, they are not exempt from this rule. Different parameters should be investigated to improve electrochemical methods for the analysis of real samples, selectivity being the most important. Inherent selectivity of dynamic electrochemical techniques is achieved when the analyte reacts in different values of applied parameters compared to potentially interfering species. In other words, the choice of applied parameter (e.g. potential in voltammetry) determines the selectivity of the measurement.

Download or read book Electroanalytical Chemistry Research Developments written by P. N. Jiang and published by Nova Publishers. This book was released on 2007 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroanalytical chemistry, as the name implies, involves the analysis of chemical species through the use of electrochemical methods. Generally, alterations are measured in the concentration of a chemical species by measuring changes in current in response to an applied voltage with respect to time. According to Faraday's law, the charge is directly proportional to the amount of species undergoing a loss (oxidation) or gain (reduction) of electrons. Constant potential amperometry, high-speed chronoamperometry, fast cyclic voltammetry (FCV) and differential pulse voltammetry (DPV) are the most common voltammetric techniques used to detect monoamine neurotransmitters (ie, serotonin, dopamine, norepinephrine). Each method has its pros and cons. In constant potential amperometry, a uniform potential is applied and the change in current is monitored as a function of time. The advantage of this technique is that the time resolution is limited only by the data collection frequency of the instrument.

Download or read book Hazardous Metals in the Environment written by M. Stoeppler and published by Elsevier. This book was released on 1992-04-13 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: The execution of detailed studies on the fate and levels of hazardous elements in the environment, foodstuffs and in human beings has become a major task in environmental research and especially in analytical chemistry. This has led to a demand to develop new methodology and optimize that already in use. The book offers the reader a general introduction to the problem areas that are currently being tackled, followed by chapters on sampling and sample preservation, strategies and applications of the archiving of selected representative specimens for long-term storage in environmental specimen banks. This is supplemented by the example of wine as a preserved - frequently, already historical - specimen which clearly reflects technological changes over time. The following chapters review sample treatment, present an overview on the most frequently and successfully applied trace analytical methods for metals and metal compounds, and introduce the increasingly important methods for identifying and quantifying metal species in sediments and soils (speciation). The chapters in the second part of the book provide data on analytical methods for determining the levels of toxicologically, ecotoxicologically and ecologically important elements in environmental and biological materials, including information on the separation and quantification of chemical and organomatallic species. The elements treated are aluminium, arsenic, cadmium, chromium, cobalt, lead, mercury, nickel, selenium and thallium. The final chapter treats quality assurance and the importance of the continuous use of appropriate reference materials to avoid erroneous results.

Download or read book Advanced Sensor and Detection Materials written by Ashutosh Tiwari and published by John Wiley & Sons. This book was released on 2014-06-09 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a comprehensive and interdisciplinary review of the major cutting-edge technology research areas—especially those on new materials and methods as well as advanced structures and properties—for various sensor and detection devices The development of sensors and detectors at macroscopic or nanometric scale is the driving force stimulating research in sensing materials and technology for accurate detection in solid, liquid, or gas phases; contact or non-contact configurations; or multiple sensing. The emphasis on reduced-scale detection techniques requires the use of new materials and methods. These techniques offer appealing perspectives given by spin crossover organic, inorganic, and composite materials that could be unique for sensor fabrication. The influence of the length, composition, and conformation structure of materials on their properties, and the possibility of adjusting sensing properties by doping or adding the side-groups, are indicative of the starting point of multifarious sensing. The role of intermolecular interactions, polymer and ordered phase formation, as well as behavior under pressure and magnetic and electric fields are also important facts for processing ultra-sensing materials. The 15 chapters written by senior researchers in Advanced Sensor and Detection Materials cover all these subjects and key features under three foci: 1) principals and perspectives, 2) new materials and methods, and 3) advanced structures and properties for various sensor devices.
