Proces:
Mechasim:
HS- react with complexing ferric salt, HS- was oxidized elemental sulfur, while Fe3+L was reducted to Fe2+L, and oxidized into Fe3+L again after inject air into regenerating tank, thus cyclic sulfur removal was realized.
1). H2S (g) →H2S 
2). Fe3+(L)+OH- →Fe3+(OH-)(L)
3). H2S(l)+Fe3+(OH-)(L)→Fe3+(SH-)(EDTA)+H2O
4). Fe3+(SH-)(L)+Fe3+(OH-)(L)→[Fe3+(L)]2S2-+H2O
5). [Fe3+(L)]2S2-→2Fe2+(L)+S
Remark: L is complex compound

Complexing desulfurizer is complex of transition metal and ligand, while transition metal provide empty orbit, and ligand provide lone pair electrons, which formed the stable complexing system. Due to the cost-effective, wet oxidation desulfurization widely used in industrial area.
