Abstract The present report deals with a very selective, facile and precise method for rapid separation of the trace copper in aqueous samples using octadecyl silica bonded phase membrane disks modified by N,N’-diethylethylendiaminyl,2,6-pyridinedicarboxylate (DDPD) combined with flame atomic absorption spectrometric determination. Besides, synthesis and spectral characterization of DDPD have been described in detail. All the affecting experimental variables such as pH, amount of modifier, eluent type, sample and eluent flow-rate, interfering ions and disk capacity were also investigated. The target analyte (trace copper) was quantitatively retained at pH = 4, and eluted with 6 ml of HNO3 0.5 M applying flow rates of 45 ml min−1 and 12 ml min−1 for analyte passage and elution steps, respectively. The proposed method also permits an enrichment factor of about 500 and a detection limit of 0.005 ng ml−1. The method has been successfully applied for isolation and determination of copper in different aqueous, real samples, peppers and standard alloys. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analytical Chemistry Letters Taylor & Francis
