| Abstract | ||
| Simple method for determination of Pb in natural water by flame atomic absorption spectrometry (FAAS) has suggested .The calibration graph for lead was linear in the range (0.02- 0.1) µg ml-1and the detection limit was 0.4 x 10-3 µgL-1. For the determination of microamounts of lead in natural water, an extraction technique was developed. Lead was retained as Pb-dithizone complex and extracted into carbon tetrachloride. The preconcenration, liquid – liquid extraction, optimal conditions for the extraction of lead complex were determined. The FAAS method was applied to the determination of Pb in natural water from different areas of Missan province. The obtained results demonstrated that the procedure could be successfully applied for the analysis of water samples with satisfactory accuracy. | ||
