“…In this work, a voltammetric method based on the electrochemical reduction of the oxime group of the hydroxyoximes DSAO and HNAPO to give the corresponding amines 16 is proposed. The voltammetric behaviour of DSAO in hydro-alcoholic solutions using differential pulse voltammetry (DPV) is reported.…”

A differential pulse voltammetric method using a hanging mercury drop electrode (HMDE) was optimized for the determination of 5-dodecylsalicylaldoxime in hydro-alcoholic solutions using factorial and central composite designs. The Taguchi design methodology was used to extend the formerly optimized method to the determination of 2?-hydroxy-5?-nonylacetophenone oxime. The method was successfully applied to quantify 5-dodecylsalicylaldoxime and 2?-hydroxy-5?-nonylacetophenone oxime in samples of commercial extractants over the concentration range 0.05?2.45 and 0.07?0.82 mg L-1, respectively, with detection limits of 0.034 and 0.019 mg L-1, respectively.

The polarographic behavior of I-[2-phenyl-2-(hydroxyimino)ethyIl-6-methylquinolinium chloride has been investigated. The pH of the Britton-Robinson buffer, used as supporting electrolyte, influences the position of the half-wave potential which shifts towards more negative values with increasing pH. Well defined, diffusively controlled cathodic waves were observed in acid medium far the overall irreversible reduction of the azomethine group to a primary amino group. A single four-electron reduction is obtained and a mechanism has been proposed for the reduction. The ratio id/c remains constant and allows a rapid and reproducible determination of the compound (CV = 0.54-2.10%).Reduktion und Bestimmung des 1-(2-Phenyl-2-hydroxyiminoethyl)-6-methylchinoliniumchlorids an der tropfenden Quecksilber-Elektrode Das polarographische Verhalten der Titelverbindung wird untersucht. Der pH-Wert des als Hilfselektrolyt verwendeten Britton-Robinson-Puffers beeinflußt die Lage des Halbwellenpotentials, das mit steigendem pH-Wert zu negativen Werten verschoben wird. Im sauren Milieu werden gut ausgeprägte diffusionskontrollierte Kathodenwellen für die irreversible Reduktion der Azomethingruppe zum primären Amin beobachtet. Ein 4-Elektronen-Reduktionsschritt tritt auf, ein Mechanismus wird vorgeschlagen. Das Verhältnis id/c bleibt konstant und erlaubt eine schnelle und reproduzierbare Bestimmung der Titelverbindung (CV = 0.54-2.10 %).
