    Description / Table of Contents: Zusammenfassung Die Flüssigkeits-Szintillationszählung zur Bestimmung von14C-markiertem Ametryn in Dünnschichtchromatogrammen wurde eingehend geprüft. Alterung, Löschungseffekt von Trägersubstanz und Adsorptionsmitteln, Temperaturbeständigkeit der Verbindung in adsorbiertem Zustand wurden untersucht. Die Reproduzierbarkeit beträgt 1 bis 2%, die Nachweisgrenze 0,005μg pro Tüpfel, das Signal-Hintergrund-Verhältnis 3∶1. Zur Lokalisierung der Flecken wurde die Fluoreszenzlöschung herangezogen. Die Ausbeute nach 30 Minuten Entwicklung auf Silikagelplatten war ungefähr 90% Ametryn, unabhängig vom Laufmittel. Bei zweidimensionaler Arbeitsweise wurden 75% wiedergefunden. Die Ausbeute aus Wasser- und Bodenproben lag zwischen 78 und 88%.
    Notes: Summary The use of the liquid scintillation counting method for the determination of14C labelled ametryne on thin-layer chromatograms has been thoroughly investigated. Aging, quenching effect of carrier and adsorbents as well as temperature stability of the compound in the adsorbed state have been studied. The method has a reproducibility of 1 to 2% and a detection limit of 0.005μg per spot at a 3 ∶ 1 signal to background ratio. Fluorescence quenching was used for the location of spots on the chromatogram. Recovery studies were carried out by this method. After 30 minutes development on a chromatoplate coated with silicagel, about 90% of the ametryne was recovered independent of solvent system used. About 75% of the ametryne was recovered from a two-dimensional chromatogram. Recoveries of ametryne from water and soil samples ranged between 78 and 88%.

    Notes: Abstract Molten bisulphates form an interesting class of low-temperature fused salts which quench to form glasses; some technical and theoretical applications of these systems are discussed. The NaHSO4KHSO-4 eutectic (46.5% KHSO4, m.p. 125°C,T g 25°C) is easy to study since at lower temperatures decomposition of the melt is retarded and supercooling readily occurs. The solvent properties of this eutectic towards both inorganic and organic solutes have been investigated. The oxidation states available to transition and post-transition metals were studied spectrophotometrically and voltametrically; the results show a very restricted pattern of redox chemistry. The (abbreviated) electrochemical series is V(V)/V(IV)〉Mn(III)/Mn(II)〉H(I)/H2(O)〉Ag(I)/Ag(O)〉Mo(VI)/Mo(V)〉 Hg(I)/Hg(O)〉Cu(II)/Cu(O)〉Zn(II)/Zn(O). The Hammett acidity function,H 0, was measured as in the range −1 to −2. Various factors influencing redox reactions in the melt are discussed.
