Popis: | Modified lignosulfonates are shown to be an effective peptising agent in the synthesis of nanosized colloids of magnetite in aqueous media. The effects of lignin modification by nitrosation reaction, as well as the effects of molecular weight and lignosulfonate type, are explored. The results show that relative magnetic permeability (RMP) as high as 35 g/g Fe is achieved when using high molecular weight nitrosated lignosulfonates from the acid sulfite pulping process. |
