  • Which oxidizing agent is used in the synthesis of PFS?
  • The synthesis of PFS commences with the oxidation of ferrous sulphate (5.59 × 10 −3 M as Fe) to ferric sulphate in highly acidic conditions (H 2 SO 4, 96 wt%). The oxidising agent was nitric acid (HNO 3, 65 wt%). FeSO4+1/2SO42−+oxidising agent→1/2Fe2(SO4)3(Step 1. Oxidation)
  • 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...
  • Does polyferric sulphate remove algae?

  • Can polymeric iron sulphate be used for industrial effluent treatment?
  • The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants .
