In this study Cu2+/1,5-diphenylcarbazite precipitate was used for coprecipitation of palladium(II) prior to its flame atomic absorption spectrometric (FAAS) determination. The recovery values of analyte ion were higher than 95%. The parameters including pH, sample volume, centrifuge time, amounts of copper(II) and 1,5-diphenylcarbazite were optimized for the quantitative recoveries of the analyte. The relative standard deviation of Pd(II) was found to be 6.3%. The limit of detection was calculated as 0.40 mu g L-1. The validation of the procedure was checked by the analysis of CRM-SA-C (standard material). The presented coprecipitation procedure was successfully applied to anodic slime and gold ore samples for determination of analyte ion. (C) 2010 Elsevier B.V. All rights reserved.
