Depending on the type of the second monomer paired with acrylamide, di-block polyacrylamide (DCPAMs) exhibit varying levels of toxicity, degradability, and performance . In this study, we utilize methylated dimethyl-aminoethyl acrylate as the second monomer in the polymer, chemically referred to as poly(acrylamide-[2-(methacryloyloxy)ethyl] trimethylammonium), due to its non-toxicity, slow degradability, and straightforward synthesis process . This polymer has also been widely utilized in wastewater treatment . Henceforth, we refer to this polymer as DCPAM.
