Cationic flocculant of quaternary ammonium salt of lignin was synthesized using sulphate lignin from papermaking black liquor.The decolourizing performance of quaternary ammonium salt of lignin and effects of different catalysts on the synthesis were studied.Quaternary ammonium salt of lignin was investigated through infrared spectrum(FTIR).Flocculation performance of the salt applied to dye liquor of high concentration and high colority has been quantitatively analysed. Results indicate that… CONTINUE READING
