    polarographic reducibility of nitro group [ 7], modern electroanalytical methods, especially very sensitive techniques at mercury electr odes, could be expected to satisfy high requirements.   Metrohm Application Bulletins and Notes. AB 70 Polarographic determination of nitrate in water samples, soil and plant extracts, vegetable juice, meat and sausages, liquid manure, fertilizers, etc.

    In polarography the microelectrode is a dropping mercury electrode (D ME). The method is used for the analysis of electroreducible or oxidizable metal, ion or organic substance (electroactive species). Electroactive species is transferred into a polarographic cell (e lectrolytic cell) where voltage is applied to the electrodes. Bibliography Includes bibliographical references and index. Contents. Contemporary trends of development in analytical chemistry-- sampling and preparation of analysis - concentration techniques-- sensor signals processing in analytical instrumentation-- modern polarographic methods in chemical analysis-- analytical electrophoresis-- contemporary trends in applications of ion selective.

    Special attention will be given to the use of modern polarographic and voltammetric techniques on the mercury and different types of solid electrodes, together with their some practical applications. The main drawbacks and limitations of these methods will also be by: 6. Electroanalytical methods are a class of techniques in analytical chemistry which study an analyte by measuring the potential and/or current in an electrochemical cell containing the analyte. These methods Modern polarographic methods in analytical chemistry. New York: M. Dekker.

Description: This book provides up-to-date discussion of modern polarographic methods, with examples and experimental details. It is designed for the practicing analyst and a factor in bringing the reincarnated area of analytical chemistry into a new and healthy maturity.

Modern polarographic techniques renders in further possible to determine submicrogram quantities of pro teins (Vorlickova and Palecek, ) in nucleic acid samples (for an analysis by means of differential pulse polarography several microarams of a nucleic acid is sufficient) and nucleic acid bases (Palecek and 3elen, ) at concentrations substantially lower than those detectable with the aid of the conventional UV-spectrophotometric by: 1.

The most important of modern polarographic techniques is that of differential pulse polarography. Here a 25 or 50 mV amplitude pulse is superimposed at fixed time intervals on the normal linear increasing voltage of 2 or 5 mVs −1, with the mercury drop being dislodged mechanically and so arranged that the pulse occurs once during the lifetime of each drop (see Figure ).

The simple principle of polarography is the study of solutions or of electrode processes by means of electrolysis with two electrodes, one polarizable and one unpolarizable, the former formed by mercury regularly dropping from a capillary tube.
