Electrochemical determination of 5-dodecylsalicylaldoxime and 2'-hydroxy-5'-nonylacetophenone oxime in commercial extractants

María P. Elizalde, María del Sol Rúa, Marta Huebra, Begoña Menoyo


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, respectively, with detection limits of 0.034 and 0.019 mg/L, respectively.
