TL;DR: In this paper, a linear relationship was found between nitrite concentration and the absorbance at 580 nm of the chromium (III) species produced, which was used to determine the nitrite.

TL;DR: Low molecular weight cadmium, copper, and zinc binding protein has been isolated from the musselMytilus edulis in the Cadmium polluted areas of Corio Bay adjacent to Melbourne and suggests that it belongs to the metallothionein family of metal binding proteins.
Abstract: Low molecular weight cadmium, copper, and zinc binding protein has been isolated from the musselMytilus edulis in the cadmium polluted areas of Corio Bay adjacent to Melbourne. Its molecular weight and other properties suggest that it belongs to the metallothionein family of metal binding proteins. Its synthesis may have been induced in the cyctoplasmic solutions of the cells as a regulatory mechanism to avoid intoxication by excess uptake of any of the metals.

TL;DR: In this article, high-performance liquid chromatography separation by isocratic elution of a wide range of substituted phenols, including the so-called priority pollutants, is investigated, by careful selection of the eluting solvent mixture, the method may be adapted for the routine analysis of phenols particularly phenolic aqueous environemental samples.

TL;DR: In this paper, the thermal decomposition products of copper dimethyldithiocarbamate and copper diethyldithium carbamate have been semi-quantitatively analyzed by a combined gas chromatography-based technique.
Abstract: The thermal decomposition products of copper dimethyldithiocarbamate and copper diethyldithiocarbamate have been semi-quantitatively analyzed by a combined gas chromatography — mass spectrometry technique and thermal decomposition mechanisms for both complexes are proposed. The fragmentation pathway is strongly influenced by the nature of the terminal alkyl group attached to the dithiocarbamate moiety.

TL;DR: In this paper, high-performance liquid-chromatographic (HPLC) methods for the separation, identification and quantification of selenite, selenate, hydrogen selenide, methaneselenol, bis(organothio) selenides, trimethylselenononium salts, SE derivatives of carbohydrates and other miscellaneous selenium compounds are summarized.
Abstract: Selenium appears in the natural selenium cycle in the form of several organic and inorganic compounds. The biologically beneficial and deterimental effects of ‘selenium’ must be ascribed to particular selenium compounds. The identification and quantification of selenium compounds in biological and environmental samples is required for an understanding of the role of selenium. The high-performance liquid-chromatographic (HPLC) methods for the separation, identification and quantification of selenite, selenate, hydrogen selenide, methaneselenol, bis(organothio) selenides, trimethylselenonium salts, selenonamino-acids, selenium derivatives of carbohydrates, selenoproteins, selenonucleosides and other miscellaneous selenium compounds are summarized (193 references) and pertinent detection modes discussed. Advantages and disadvantages of the methods are pointed out. The literature is covered since 1974, the year of the first publication in this field.

TL;DR: Nine non-noble-metal catalysts from five different laboratories were investigated for the catalysis of O(2) electroreduction in an acidic medium, and the nitrogen and metal seem to be present in sufficient amounts in the NNMCs and do not limit activity.
Abstract: Nine non-noble-metal catalysts (NNMCs) from five different laboratories were investigated for the catalysis of O2 electroreduction in an acidic medium. The catalyst precursors were synthesized by wet impregnation, planetary ball milling, a foaming-agent technique, or a templating method. All catalyst precursors were subjected to one or more heat treatments at 700−1050 °C in an inert or reactive atmosphere. These catalysts underwent an identical set of electrochemical characterizations, including rotating-disk-electrode and polymer−electrolyte membrane fuel cell (PEMFC) tests and voltammetry under N2. Ex situ characterization was comprised of X-ray photoelectron spectroscopy, neutron activation analysis, scanning electron microscopy, and N2 adsorption and its analysis with an advanced model for carbonaceous powders. In PEMFC, several NNMCs display mass activities of 10−20 A g−1 at 0.8 V versus a reversible hydrogen electrode, and one shows 80 A g−1. The latter value corresponds to a volumetric activity of ...

TL;DR: In this article, a review of the electrochemistry and electroanalytical applications of carbon paste-based electrodes, sensors, and detectors is presented on the occasion of the half-of-century anniversary since the discovery of carbon powder.
Abstract: This article reviews the electrochemistry and electroanalytical applications of carbon paste-based electrodes, sensors, and detectors on the occasion of the half-of-century anniversary since the discovery of carbon paste. The review (with 333 references) has been prepared in the form of a retrospective compilation presenting the field by means of various facts, notes, data, surveys, and summaries, including numerous rarities or curiosities that illustrate the individual achievements and milestones. Carbon paste-based electrodes are discussed in their entirety by covering all important areas of the field, starting from basic characterization of carbon paste as the electrode material, via its typical physicochemical and electrochemical properties or specific features, up to a representative documentation of their applicability in electrochemical and electroanalytical measurements.

TL;DR: A review of the use of carbon paste as an electrode maaterial for electrochemical sensors can be found in this paper, which covers mainly publications which appeared during the period 1990-1993.
Abstract: A review is presented dealing with the use of carbon paste as an electrode maaterial for electrochemical sensors (311 references). It covers mainly publications which appeared during the period 1990–1993; numerous applications demonstrate the widespread applicability of carbon paste in the field of electrochemical analysis, such as voltammetry, amperometry, and potentiometry, but also as an electrode for electrochemical detectors in flow systems.
