摘要：

A solid phase extraction method for enrichment-separation and the determination of cobalt (Co2+), copper (Cu2+), nickel (Ni2+), zinc (Zn2+) and lead (Pb2+) ions in real samples has been proposed. The influences of some analytical parameters like pH, flow rate, eluent type and interference of matrix ions on recoveries of analytes were optimized. The limits of detection were found in the range of 1.6-3.9 mu g L-1 while preconcentration factor for all understudy metal ions were found to be 166 with loading half time (t(1/2)) less than 10 min. The procedure was applied for the enrichment-separation of analyte ions in environmental samples with recoveries higher than 94.8% and relative SD <4.9% (N = 5).
