Research Progress in Ferrite Series Inorganic Polymer Cationic Flocculants

Ferrite series inorganic polymer cationic flocculants are the combination product of intermediates in the hydrolysis of metal ions （iron ion, etc.） with negative charge sol particles and different anion. In this paper, the preparation methods of ferrite series inorganic polymer cationic flocculants were introduced, including poly phosphate ferric sulfate flocculant, polyferric silicate flocculant, polysilicate aluminum ferric flocculant, polymeric aluminum-ferric chloride flocculant. Application of these ferrite series inorganic polymer cationic flocculants in treatment of wastewater including dyeing wastewater, papermaking wastewater, food industry wastewater and pharmaceutical wastewater was discussed. At last, the future research direction of preparation method was proposed.
