Residue Reviews/RĂĽckstandsberichte


Book Description

That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.

Thermodynamic Measurement Techniques


Book Description

This book offers various techniques for measurement of thermodynamic quantities of materials such as enthalpy, free energy, and entropy. Techniques described herein include calorimetry, chemical equilibria, vapour pressure, and electrochemical analysis. The book covers general and solution thermodynamics in Chapters 1 and 2, respectively, and highlights the significance of various thermodynamic quantities required for materials characterization and development in Chapter 3. The author goes on to discuss different thermodynamic measurement techniques in detail (Chapters 4-8) together with a set of more than fifty worked-out problems related to classical as well as solution thermodynamics and measurement techniques. (Chapter 9). Topics include but are not limited to the following: The significance of various thermodynamic data required for selection and characterization of materials. The physicochemical principles involved in various thermodynamic measurement and on the evaluation of thermodynamic data by phase diagram analyses. The unique combination of calorimetry and chemical equilibrium for simultaneous determination of partial molar enthalpy and partial molar free energy of hydrogen in metals and alloys. The special technique based on the combination of vapor pressure and electrical conductivity to study the effect of tellurium vapor pressure on the mode of conduction in polycrystalline cadmium telluride.




Physico-Chemical Analysis of Molten Electrolytes


Book Description

Physico-Chemical Analysis of Molten Electrolytes includes selected topics on the measurement and evaluation of physico-chemical properties of molten electrolytes. It describes the features, properties, and experimental measurement of different physico-chemical properties of molten salt systems used as electrolytes for different metal production, metallic layer deposition, as a medium for reactions in molten salts.The physico-chemical properties such as phase equilibria, density (molar volume), enthalpy (calorimetry), surface tension, vapor pressure, electrical conductivity, viscosity, etc. are the most important parameters of electrolytes needed for technological use. For each property the theoretical background, experimental techniques, as well as examples of the latest knowledge and the processing of most important salt systems will be given.The aim of Physico-Chemical Analysis of Molten Electrolytes is not only to present the state of the art on different properties of molten salts systems and their measurement, but also to present the possibilities of modeling molten salt systems, to be able to forecast the properties of an electrolyte mixture from the properties of the pure components in order to avoid experimentally demanding, and in most cases also expensive measurements.This book fills a substantial gap in this field of science. Also documententing the latest research in molten salts chemistry and brings new results and new insights into the study of molten salts systems using the results of X-ray diffraction and XAFS methods, Raman spectroscopy, and NMR measurements.* This book fills a substantial gap in this field of science* Serves as a invaluable reference for all people working in the field of molten salts chemistry* Describes fundamentals of the various properties of molten electrolytes
