Summary of the extent of Fe leaching from the tested Fe0 specimens after 55 leaching events.
| Leaching rate | S15 | iPuTec | S69 | sponge iron | iPuTec (2) | |
|---|---|---|---|---|---|---|
| Daily | (mg) | 7.6 | 8.6 | 9.0 | 9.6 | 11.4 |
| Total | (mg) | 420 | 475 | 497 | 530 | 628 |
| Total | (%) | 42.0 | 47.5 | 49.7 | 53.0 | 31.4 |
The daily leaching is the sum of the leaching mass divided by 55, ‘iPuTec (2)’ corresponds to the experiment using 2.0 g of Fe0.
