The molecular weight distribution of SEPS in groups with different initial Pb2+ concentration.
| Pb2+ concentration (mg/L) | Mw (Da) | Mn (Da) | Mw/Mn |
|---|---|---|---|
| 0 | 1.499 × 106 | 1.238 × 106 | 1.211 |
| 200 | 2.860 × 106 | 2.586 × 106 | 1.106 |
| 4.994 × 104 | 3.994 × 104 | 1.250 |
Mn apparent number average molecular weight, Mw weight average molecular weight.
