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.

synthesis and characterization of acrylamide‐based anionic,as expected, the 1 h-nmr and 13 c-nmr confirmed the presence of both monomers in the copolymers. 3.2. determination of anionic degree of copolymers. the number of anionic monomer content of each sample is known as the anionic degree. the anionic degree obtained from 13 c-nmr peak integration and titration methods are given in table 1.

best practices guidance for the use of anionic polyacrylamide

largest tss reductions observed in polymer systems on sept. 9 (88%) and dec. 4 (95%). polymer tank system with the sediment bag achieved largest tss reduction (95%) and lowest effluent tss concentration (13 mg/l). for controls, effluent tss consistently 25 mg/l (ranging from 74 to 153 mg/l), even when percent tss reduction was high.
