Reducing dissolution of MnO2 nanofibers by doping with ferric ion
MnO 2 nanofiber was found to possess high adsorption capacities for heavy metal ions such as, arsenic and lead, in water due to its high specific surface area (SSA) and high surface activity. However, a significant amount of manganese was found to leach from MnO 2 nanofibers. Reducing MnO 2 dissolut...

nanofiber was found to possess high adsorption capacities for heavy metal ions such as, arsenic and lead, in water due to its high specific surface area (SSA) and high surface activity. However, a significant amount of manganese was found to leach from MnO
2
nanofibers. Reducing MnO
2
dissolution is very important for improving its applications in drinking water treatment. In this study, MnO
2
nanofiber was doped with Fe
3+
to reduce its dissolution in water. Dissolution tests were conducted on un-doped and Fe-doped MnO
2
nanofibers. The results revealed that doping with Fe
3+
significantly reduced MnO
2
dissolution. SSA and defects of MnO
2
materials were analyzed by BET and XRD methods. The effects of Fe
3+
on MnO
2
dissolution were discussed and the optimal dopant amount was identified. |
