anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Fabricating an anionic polyacrylamide (APAM) with an anionic block structure for high turbidity water separation and purification - RSC Publishing

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 (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template.

Polyaluminium Chloride and Anionic Polyacrylamide Water Treatment Residuals as a Sorbent for Cd2+ and Zn2+ in Soils | Water, Air, & Soil Pollution

Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd2+ and Zn2+ from aqueous solutions by batch adsorption studies. The maximum adsorption capacity obtained from Langmuir modeling was 85.5 mg Cd2+/g PAC-APAM WTRs or 25.6 mg Zn2+/g PAC-APAM WTRs. A Dubinin-Radushkevich (D-R) model
