Abstract

 Optimal conditions for lignin coagulation in aqueous medium by various coagulants was studied by varying pH, amount of coagulant added and settling time. The coagulants used are aluminium sulphate (alum), polyacrylamide (PAM) and chitosan. It was observed that the formation of floes was rapidly taking place after the addition of way in lignin contaminated water. This indicates the occurrence of the fast coagulation process. It was also found that chitosan, an ionic coagulant in acetic solution, was the best coagulating agent at pH 5. Up to 90% of lignin and chemical oxygen demand (COD) as well as 80% of color were reduced when 0.50 g/L of chitosan was added in solutions containing lignin and settled them for 20 min. For polyacrylamide, a nonionic polymer, its coagulating efficiency of lignin was poor. the reduction of lignin, COD and color by PAM were less than 10% whereas the addition of alum in lignin solution samples reduced more than 70% of lignin and COD with color reduction up to 85%.

Keywords: lignin, coagulation, chitosan, alum, polyacrylamide
