Abstract Flocculant based on natural polymer has attracted more attention duo to its rich source, low cost and eco-friendliness. In this paper, we adopted a synthetic monomer of acrylamide to graft chitosan and lignin together by microwave assisted method. Flocculation studies showed that chitosan-acrylamide-lignin (CAML, 2 g:2 g:2 g) terpolymer exhibited maximum percentage removal of 99.3%
