Evaluating Prussian blue analogues MII3[M III (CN) 6 ] 2 (M II = Co, Cu, Fe, Mn, Ni; M III = Co, Fe) as activators for peroxymonosulfate in water

[Fe(CN) 6 ] and [Co(CN) 6 ]-based Prussian blue analogues (PBAs) were prepared with various metal ions ( i.e. , Co, Cu, Fe, Mn and Ni) and evaluated as catalysts to activate an important oxidant, peroxymonosulfate (PMS).
