  • About the Edition

    Ion-selective electrodes (ISEs) have a wide range of applications in clinical, environmental, food and pharmaceutical analysis as well as further uses in chemistry and life sciences. Based on his profound experience as a researcher in ISEs and a course instructor, the author summarizes current knowledge for advanced teaching and training purposes with a particular focus on ionophore-based ISEs. Coverage includes the basics of measuring with ISEs, essential membrane potential theory and a comprehensive overview of the various classes of ion-selective electrodes. The principles of constructing ISEs are outlined, and the transfer of methods into routine analysis is considered. Advanced students, researchers, and practitioners will benefit from this expedient introduction.

    Search for:. Polymer membrane electrodes: An alternative to wet liquid membrane electrodes is to use a polymeric membrane, Ion-Selective Electrodes book is composed of a polymer such as polyvinylchloride PVCa plasticizer, and the ion carrier or exchanger. Although this volume is not intended to be exhaustive, we have attempted to produce a "stand alone" text dealing with all major current developments. Also included is a chapter on advances in calibration procedures, the development of long range sensors, and the use of ion-buffers for extending known calibration ranges—all of which are essential to obtaining and extending the linear ranges of ISEs.

    Figure 4. Tissue-Based Electrode. We will call the interfering ion j with corresponding activity Aj and charge zj. Enzyme Determinations. The final prices may differ from the prices shown due to specifics of VAT rules About this book We continue in this second volume the plan evident in the first; i.

    Immobilized Enzyme Systems. Furthermore it will probably only be effective for ions with selectivity coefficients less than 1 and require a fairly uniform amount of interferent in the samples. For many applications these interferences are insignificant unless there is a high ratio of interfering ion to primary ion and can often be ignored. Textbooks usually cover some more or less narrow subject in maximum depth.

Ion-Selective Electrodes by Konstantin N. Mikhelson Download PDF Ebook

Inhibitor Determination. This electrode is used in one of the experiments outlined in the Experimental section.

The Principles of Ion

The response of these electrodes is highly selective and they have replaced many liquid membrane electrodes. Current Trends. As you can see from the equation, the smaller the kij values, the less impact the Ion-Selective Electrodes book ion will have on the measured potential.

In Ion-Selective Electrodes book case however, the chloride ion can be removed from solution by precipitating as the sparingly soluble silver chloride. Characteristics of Immobilized Enzymes 23 3. Indeed, since some of the theoretical approaches are not yet universally agreed on, each of the first five chapters deals with theory and principles of the nature and behavior of ion-selective electrodes from the vantage point of the authors' own experience and understanding.

About this book Introduction Ion-selective electrodes continue to be one of the more excIting developments in electro analytical chemistry in the last 10 years. Preparation of Electroactive Species. Selectivity coefficients for some of the electrodes previously discussed are listed below.

MIS Structure. This is a variable factor and depends on the valency and ionic radius of the measured ion and the total ionic strength of the solution. Neutral-Carrier-Based Electrodes. Methods of Immobilization.

Glass electrodes can also be constructed that are sensitive to other cations such as sodium. Amino Acid Electrodes 41 4. Let me explain the difference. Penicillin Electrodes. Amygdalin Electrodes 39 4.

7: Ion Selective Electrode Analysis

Later I organized my lecture notes into the? Until recently, these interferences have limited the use of the ammonium ISE to only those applications where a high NH4 to K ratio can be guaranteed. The cation exchanger is dissolved in an organic solvent and held in a porous compartment between the analyte solution and internal reference calcium chloride solution.

This means that an equal concentration of chloride would only add about 0. In reality, ion-selective electrodes can experience interferences by responding to Ion-Selective Electrodes book presence of other ions.

Ion-Selective Electrodes book update 21 Oct The three main limitations on Ion Selective Electrode measurements are the effect of interference from other ions in solution, the effect of the ionic strength of the solution reducing the measured activity relative to the true concentration at high concentrations, and potential drift during a sequence of measurements.

Thus, the relationship between potential difference and ion concentration can be determined by measuring the potential of two solutions of already-known ion concentration and a plot based on the measured potential and logarithm of the ion concentration. Calibration of Coated Wire Electrodes. Electrochemical cell for a potentiometric measurement with an ISE.

After the reader is aquainted with the basic problems involved, the third section deals with individual ion-selective electrodes; their properties, handling and methods of pre paration.

During the measurement, there is little to no current flow. The membrane is composed of a silicate glass. If the primary ion for which the electrode is sensitive is A and the interfering ion is B then a selectivity coefficient of 0.

Personal information is secured with SSL technology.A wide variety of neutral carrier based ion-selective electrodes has been introduced and Js in routine use in analytical chemistry.

The actual state of the art of such potentiometric sensor applications in clinical chemistry and neurophysiology is summarized. Ion-Selective Electrode Determination of Fluoride Ion I.

Introduction A. Ion-Selective Electrodes The amount of a specific ion contained in an aqueous Ion-Selective Electrodes book can be determined by direct potentiometric measurement of Ion-Selective Electrodes book voltage of a galvanic cell such as shown below.

reference electrode analyte solution ion selective electrode. Jan 12,  · Ion-selective electrodes are widely used for non-destructive, rapid, sensitive and precise determination of many ions in a great variety of media and therefore, provide a powerful analytic tool.

Since the appearance of the first edition of Professor Koryta's book in progress in the whole field of ion-selective electrodes has been rapid and Cited by: As indicated by their name, pdf electrodes possess a high degree of selectivity.

The selectivity of the ISE is determined by the composition of the membrane. Ideally the membrane allows the uptake of only one specific ion into it.

The analyte ion may be a cation or an anion.Created Date: 11/13/ AM.ion-selective electrode: a potentiometric electrode that develops a potential in ebook presence of one ion (or class of ions) but not in the presence of a similar concentration of other ions.
