| Abstract: | Lignin was modified through Mannich reaction to compound a kind of cationic surfactant lignin-amine. The nitrogenous content and the modification rate of the modified lignin was measured by elementary analysis and electrophoresis. It is a liner relation between them. The surface activity of lignin-amine has been studied. The main factors which affected the nitrogenous content and the modified rate were determined by adopting three factors two power-regression orthogonal design. The study is useful in controlling environmental pollution. |
