Abstract

Preconcentration of Cd(II) and Pb(II) was carried out by using column solid phase extraction method. Amberlyst 15 was used as solid phase for these analytes. The optimum extraction conditions such as pH (4), type and volume of eluent (5mL of 2mol L-1 HNO3) sample flow rate (1mL min(-1)) and sample volume (100mL for Cd(II) and 750mL for Pb(II)) were determined. The recoveries were found for Cd(II) and Pb(II) as 104%+/- 1% and 102%+/- 2%, respectively. The limit of detections were found as 0.23 mu g L-1 for Cd(II) and 0.13 mu g L-1 for Pb(II). The effects of foreign ions were also studied. The method was validated by analyzing standard reference material and spiked water samples. Percent relative error and relative standard deviation were below 3% and 4%, respectively.
