Abstract Background and Objectives:In this project‏‏‏‏‏‏ we have reported a solid phase extraction method for determination of trace amount of lead in water samples. Material & Methods: The column loaded with root of Glycyrrhizaglabra. The effect of different variables such as reagent concentration, flow rate and interfering ions on the recovery of the analyte was investigated using atomic adsorption. The calibration graph was linear in the range 10-120 ng/mL of lead in the initial solution. Results: Detection limits was 2/15 ng/mL (n= 6) and relative standard deviation of 20 and 60 ng/mL were 3.04 and 4.75% respectively. Conclusion: This procedure was successfully applied to the determination of lead in waste water and samples in Solid Phase extraction.

Keywords: Solid phase extraction, Lead, Industrial wastewater, Determination.
