    Separation and Preconcentration of Copper Ion by Micelle-Mediated Extraction in Aqueous Samples by F. Ahmadi, A. Khanmohammadi, Z. Tavakoli

    Published 2009-01-01
    “…At pH 5.7±0.3, preconcentration of only 15 mL of sample in the presence of 0.06% (w/v)Triton X-114 and 1.5 mM DFID permitted the detection limits of 1.5 ng mL−1 for copper. The enrichment factor was 39 for copper. The proposed method has been applied to the determination of copper in various samples and a standard reference material.…”
