Preparation and Characterization of Solid Composite Polymeric ferric sulfate
1.Introduction The production and the application of inorganic polymer flocculants (IPF) are increasing rapidly throughout the world. As the merits of IPF are reflected in they shows superior efficiency compared to traditional salts and much lower cost than organic polymer flocculants1. Al (Ⅲ) and Fe (Ⅲ) coagulants are two principal inorganic coagulants used in wastewater treatment. However, aluminum is suspected harmful to human and living organisms2. Thus, ferric ions are often the coagulant of choice to destabilize colloidal and suspend solids. PFS is a relatively new polymeric coagulant which contains a range of pre-formed Fe (Ⅲ) hydrolysis species of high positive charge and medium to large molecular weights. In this paper, we prepared a kind of solid IPF, solid Composite Polymeric ferric sulfate (SPFS), which was prepared by ferric sulfate and Na-Bentonite. The SPFS was used to treat high concentration of organic wastewater.
