| Abstract: | A novel CMC-PFSC flocculant has been synthesized with carboxymethylated chitosan (CMC) and inor-ganic polysilicate ferric chloride (PFSC) as the main raw materials. Its preparation conditions and reaction mecha-nism are studied. It is applied as flocculant to the pretreatment of seawater desalination. The results show that this compound flocculant is characterized by low dosage, better flocculating capacity and mild reaction conditions etc. CMC-PFSC flocculant can remarkably lower the seawater turbidity and COD pollution index. Therefore, the appli-cation prospects in the field of water treatment are extensive. |
