DMC-grafted cellulose as green-based flocculants for agglomerating fine kaolin particles

Novel cellulose based flocculants C-g-P (DMC) with various chain architectures are synthesized through a situ graft copolymerizationm, which is a new and simple method to employ γ-methacryloxypropyl trimethoxy silane (KH-570) as a bridge for the connection of cellulose matrix and DMC group. The results suggest that the length and quantity of cationic branch chains plays a crucial role in Kaolin flocculation due to their dramatically enhanced bridging effects.124
