Abstract:Polyferric sulfate (PFS) is classified two kinds by prepared approaches: (1) alkalization preparation of polyferric sulfate (APFS), (2) oxidation preparation of polyferric sulfate (OPFS). Different properties were discussed about OPFS and APFS, such as basicity (OH/Fe3+), zeta(Q-potential, pH. It is concluded that APFS and OPFS with same basicity have different structural feature although they have same compounds and bonds. By comparison with APFS, OPFS and ferric sulfate, OPFS has good charge neutralization capability and exhibits good coagulation performance in turbidity removal for synthetic wastewater. APFS have higher interparticle bridging capability for paper wastewater.
