Table 4. Saturation Magnetization (Ms) Values of the Magnetite Samplesa.
| Sample | Ms (emu/g) |
|---|---|
| MGP | 59.6 |
| MG4P | 20.6 |
| MGCN | 53.6 |
| MG4CN | 27.6 |
| MGSCN | 41.6 |
| MG4SCN | 16.8 |
The synthesis of MGCN/MG4CN and MGSCN/MG4SCN was carried out in the presence of 60 mmol of KCN and 60 mmol of KSCN, respectively. The seawater 4.0 Gy (high Mg2+ and SO42– concentrations) was prepared as suggested by Zaia.47
