Because of their simple preparation and low expense, carbon pastes and carbon paste electrodes are widely used in a myriad of instrumental measurements. With an emphasis on practical applications, Electroanalysis with Carbon Paste Electrodes provides a comprehensive overview of carbon paste electrodes. The text offers a comprehensive and unpreceden

V okviru raziskovalnega projekta MICROSENS, ki ga je sponzorirala Evropska komisija smo v sodelovanju z Inštitutom za kemijo/analizno kemijo (prof. dr. Kurt Klacher) na Univerzi Karla Franza v Gradcu, Avstrija, razvijali in preučevali elektrokemijske senzorje za določevanje kloridov v porni vodi betona. Razvili smo merilni sistem, ki omogoča kontinuirno zasledovanje penetracije kloridnih ionov v porozno betonsko matriko.

This book presents an exhaustive overview of electrochemical sensors and biosensors for the analysis and monitoring of the most important analytes in the environmental field, in industry, in treatment plants and in environmental research. The chapters give the reader a comprehensive, state-of-the-art picture of the field of electrochemical sensors suitable to environmental analytes, from the theoretical principles of their design to their implementation, realization and application. The first three chapters discuss fundamentals, and the last three chapters cover the main groups of analytes of environmental interest.

GFAAS has a lower detection limit compared to FAAS (1 ng Se absolute) but operates discontinuously; thus, the time required for one analysis is significantly longer and quantifications can be difficult owing to a rather limited number of spectroscopic signals forming the chromatogram. ICP-MS is very powerful and is best suited for element-specific detection. Apart from advantages such a very low detection limits (0.1 ng Se absolute) and continuous samplingm nultielement-specific detection is possible similataneously. Methods for the identification and determination of selenite, selenate, selenoamino acids and trimethylselenium salts in samples of enviromental interest are presented. [Authors' abstract].
