degradation of polyacrylamide and its significance in nature
the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning.
degradation and transfer of polyacrylamide based flocculent,monomers are only partially eliminated during polyacrylamide preparation and remain at the state of tracks in the end product. according to smith et al. , the residual content in monomers varies between 0.05 and 5 %. sodium acrylate presents no harmfulness like the polyacrylamide (stephens, 1991).
