Volumes 1 and 2 dealt with various applica- tions of high-performance liquid chromatography for the determination of trace substances. Volume 3 and the present volume have been directed toward topics in both organic and inorganic trace analysis of biological materials and environmental samples. The first article in volume 4 presents recent developments and applica- tions of ion-selective polymeric membrane electrodes for biological tis- sues and fluids. Included are applications to important ions, gas-sensing probes, enzyme electrodes and biosensors, drug detection, immunoelec- trodes, and the measurement of membrane potentials of biological sys- tems. The second article discusses recent developments in the use of solid adsorbents for preconcentrating trace organic substances, mainly pollu- tants, from air. Types of adsorbents, collection efficiencies, comparative sampling with different adsorbents, chromatographic approaches, and va- por-particle partitioning applications are presented in detail. The third article provides a detailed evaluation of X-ray emission spectroscopy for trace analysis, including the principles of the technique, descriptions of excitation and detection modes, and applications to pollutants in air, wa- ter, and other environmental substances. The fourth article follows with a similar treatment of inductively coupled plasma emission spectroscopy and its application to the determination of trace elements in surface and groundwater samples. This includes instrumentation, sampling, precon- centration, and coupling the technique with chromatography for element speciation. The final article is devoted to a comparison of neutron activa- tion analysis and proton-induced X-ray emission spectroscopy for the determination of trace elements in rain and snow. Theoretical aspects, sample preparation, intermethod comparisons, and interpretation of results are considered. This analysis complements that in the third article, resulting in the extensive coverage of X-ray spectroscopy as an analytical technique for a variety of environmental samples. These five contributions should provide the reader with much insight into the use of the various techniques described for a variety of trace analytical problems. Together they make an extremely informative and ix X Preface useful addition to this series. I would like to thank L. Ebdon, B. A. King, T. F. Bidleman, R. E. Van Grieken, J. J. LaBrecque, J. R.

INTRODUCTION Ion-selective electrodes (ISE) are devices which enable the activity of a given ion in a solution to be determined potentiometrically. They consist of a selective membrane, an internal reference electrolyte (filling solu- tion), and an internal reference electrode, which form a half-cell. An external reference electrode completes the circuit. When the ion-selective electrode is in contact with a solution of ions a potential difference is generated between the internal filling solution and the sample solution across the membrane. The potential (E) varies with ion activity according to the Nernst equation E = E° log a> e in which is0 is the standard potential, R is the gas constant, T is the absolute temperature, z is the charge on the ion, and a is the activity. x When, as is customary, the relationship is expressed as millivolts per decade change in ion activity, E is close to 60 mV at 25°C for monovalent ions. The membrane components of ISE vary greatly and may be used to define the class of ISE. An early form of ISE consisted of a liquid ion exchanger supported by a porous membrane. Moody and Thomas pio- neered a new type of ISE by incorporating the liquid ion exchanger in a nonporous polymer membrane. The new electrodes showed superior physical properties. Miniaturization of these sensors was investigated by Freiser, who introduced coated-wire ISE by coating metal wires with polymer membranes. Simon and co-workers have produced many new and highly selective electroactive materials of the neutral ligand type. Guilbault prepared new types of ISE by prefacing the selective mem- branes with enzymes and bacteria. These electrodes are capable of ana- lyzing substrates such as urea and amino acids by detection of the prod- ucts of enzyme-catalyzed reactions. The introduction of ISE to clinical medicine has been relatively slow
