Table 1 The SPE procedure for separation of Tl(I) and Tl(III) from environmental aqueous samples
From: A modified method of separating Tl(I) and Tl(III) in aqueous samples using solid phase extraction
Step | Reagent | Aim |
|---|---|---|
1 | 5Â mL-H2O | Cleaning |
2 | Sample | Introduce the sample (retain Tl(III)-DTPA and leaching Tl(I)) |
2A | 10Â mL-H2O | Elute the co-retained Tl(I) |
3 | 15 mL-HCl + SO2 | Elute the Tl(III) |
