特長Poly ferric Chloride(PFC) is a complex ferric chloride meterical. The molecular formula is the 〔Fe2 (OH)n (CLn)3 - N/2〕m, n＞2_ m=f(n). There are a lot of complex ferrous ion (〔Fe2 (OH)3〕3 , 〔Fe(H2O)6〕3 , 〔Fe3(OH)3〕6 ) in it’s water solution. So it is a good agglomerant which have a easy formation flocculate and have a good coacervation. It chemical structure is a solid network polymer which has a multinuclear complex ion. The easier hydrolysis in water and the highly efficient multinuclear hydroxyl complex negative ion have been produced during hydrolysis. In the process of a water treatment, Polymer ferrous sulfate has a good ability to neutralize surface electric charge of suspended substances, and linking suspended particle.
