title: Determination of 5-dodecylsalicylaldoxime and 5-nonylsalicylaldoxime in commercial extractants by high-performance liquid chromatography with photometric detection.
abstract: A liquid chromatographic method with photometric detection was developed and validated for the determination of 5-dodecylsalicylaldoxime in the industrial extractants LIX 622 and LIX 860 and 5-nonylsalicylaldoxime in LIX 622N, Acorga PT5050 and Acorga P5100. The limit of detection was 2.18 microg/ml for 5-dodecylsalicylaldoxime and 2.06 microg/ml for 5-nonylsalicylaldoxime. Good linear relations between the areas and the concentration of the standard injected were found in the range of 5-100 microg/ml and reproducibility studies yielded relative standard deviations lower than 6.12% in all the cases.
