Removal Of Manganese (Mn) From Aqueous Solution Using Mixture Of Ferromanganese Ore And Humus

This study examined effectiveness of mixture of ferromanganese ore (FMO) and humus to remove Mn from aqueous solution. Interactions between the FMO surface and humic substances from humus form complexation through ligand exchange, hydrogen bonding, hydrophobic interaction, etc. The complexation acts...
