Analytical figures of merit for the determination of Cd and Pb in swimming pool waters by GF AAS after preconcentration on polyurethane foam.
| Parameter | Pb(II) | Cd(II) |
|---|---|---|
| Concentration range | 1.8–40 μg·L−1 | 0.06–3 μg·L−1 |
| LOD | 0.5 μg·L−1 | 0.02 μg·L−1 |
| LOQ | 1.8 μg·L−1 | 0.06 μg·L−1 |
| Calibration equation | A = 0.0069 (Pb (μg L−1)) + 0.0047 | A = 0.16 (Cd (μg L−1)) + 0.0018 |
| r2 | 0.9976 | 0.9996 |
| Intermediary precision | 7.3% | 6.1% |
