polyacrylamide pam flocculants water treatment industrial use
high molecular weight polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity improver, among other applications.
fabricating an anionic polyacrylamide (apam) with an anionic,ultraviolet (uv)-initiated template polymerization (utp) was used as a feasible strategy to prepare a novel anionic polyacrylamide (apam) with a microblock structure. in the template copolymerization system, acrylamide and sodium allylsulfonate (sas) were used as monomers, and poly (allylammonium chloride) (paac) as a template. the
