文摘The amine unint is grafted in Lignin through Mannich reaction to compound a kind of cationic surfactant-lignin amine.The modified lignin takes on electropositive or electronegative in the diffetent pH liquors like protein does.The modifaction rate and equipotentiality of the modified lignin is measured by use of acetate fiber membrane electrophoresis.
