  • What is poly ferric sulfate (PFS)?
  • Poly ferric sulfate (PFS) with the general formula of [Fe2 (OH) n (SO4)3-n/2] m (n < 2, m > 10) is a relatively new kind of inorganic coagulant. It has been reported by several researchers that it e...
  • How is polyferric sulphate (PFS) prepared?
  • A range of effective optimal formulations of polyferric sulphate (PFS) can be prepared by a novel procedure, recently developed by the authors, involving an oxidation stage followed by a partial…
  • Is PFS a polymeric salt?
  • In polymeric form, PFS is one of the pre-hydrolysing metallic salts with the chemical formula [Fe2 (OH) n (SO4)3−n/2] m (where, n < 2, m > 10) and has a dark brownish red colour as well as is more viscous and less corrosive. PFS has an amorphous structure with small traces of crystallinity, containing both hydroxyl and sulphate functional groups.
