Abstract: A new simple and quick method has been established for separation of Cu from solutions using an extraction chromatographic resin utilizing Aliquat® 336 (commercially available as TEVA™ resin) and Cu(I). This method involves the use of a one milliliter column containing 0.33 mL TEVA™ resin on 0.67 mL Amberchrom® CG-71C acrylic resin. Copper was adsorbed on the column by forming Cu(I) with 0.15% ascorbic acid in 0.05 mol·L−1 HBr, while other major elements except Zn showed no adsorption. After removal of the major elements (Na, Mg, Al, P, K, Ca, Cr, Mn, Fe, Co and Ni), Cu was recovered using 2 mol·L−1 HNO3. The recovery yield and total blank were 102% ± 2% and 0.25 ng, respectively. To evaluate the separation method, Cu isotope ratios were determined by a standard-sample-standard bracketing method using multicollector inductively coupled plasma-mass spectrometry (ICP-MS), with a repeatability of 0.04‰ and 0.25‰ (SD), for the standard solution and the solutions from low S (<0.1% S) silicate standards, respectively.
