Polymeric flocculant based on cassava starch grafted polydiallyldimethylammonium chloride: Flocculation behavior and mechanism

- Flocculation performance of cassava grafted polyDADMAC was studied.
- Turbidity and TSS removal increased with increasing grafting percentage.
- The grafted polymer showed good removal in acidic and neutral region.
- Zeta potential results pointed to the charge neutralization mechanism.
- Flocs increased with increasing grafting percentage and molecular weight.
