摘要：

Ammonium pyrrolidinedithiocarbamate impregnated activated carbon (APDC-AC) has been used for the preconcentration of Cd(II), Cu(II), Ni(II), and Zn(II) from aqueous solution by column solid phase extraction (SPE) technique. Trace metal ions in aqueous solution were quantitatively sorbed onto APDGAC packed in a SPE column at pH 5.0 with a flow rate of 1.0 mL min(-1). The sorbed metals were eluted with I M nitric acid in acetone solution at a flow rate of 0.6 mL min(-1) and analyzed by flame atomic absorption spectrometry. The effects of sample volume, amount of APDC-AC, volume of eluent and ionic strength of working solution on metal ion recovery have been investigated. The present methodology gave recoveries from 90 to 106% and R.S.D. from 0.6 to 5.5%. (C) 2005 Elsevier B.V. All rights reserved.
