Mineral: |
Goethite |
Reference: |
DLLSM18 |
Preparation: |
prepared according to [HV99]: Freshly prepared 0.5 M Fe(NO3)3·9H2O solution was neutralized with 2.5 M NaOH at a speed of 10 mL min-1 addition under continuous stirring until the suspension reached pH 12. The obtained suspension was then aged in an oven at 60 °C for 4 days and dialyzed for about 2 weeks till the electric conductivity (EC) was lower than 10 S/cm (Venema et al., 1998). |
