    Abstract: Based on the Mannich-Reaction, a new kind of chelating flocculant grafted with diethylene triamine has been prepared from polyacrylamide (PAM), formaldehyde and diethylene triamine (DETA). Using the prepared flocculant to remove Pb 2+ from waste water was studied. Due to the introduction of chelated functional group grafted on the long chain of PAM, the as-obtained flocculant has
