polyacrylamide pam flocculants water treatment industrial use

in addition to chain scission, hydrolysis of the amide group leads to the generation of a carboxylic acid group and an ammonium ion (at low ph, see fig. 3), or the conversion of the acrylamido-2

hydrolysis of polyacrylamide and acrylic acid-acrylamide

the hydrolysis of acrylamide-acrylic acid copolymers has been studied as a function of ph and of the initial composition of the samples. our experimental results confirm the intramolecular catalysis by neighbouring undissociated carboxylate groups for 3 ph 5, as already demonstrated by smets et al., and the catalysis of oh − ions with autoretarded kinetics for ph 11.

alkaline hydrolysis of polyacrylamide researchgate,it is important to investigate the hydrolysis degree of polyacrylamide and its extent at high temperatures of 120 °c. pam undergoes alkaline hydrolysis under high temperatures to produce

hydrolysis-induced large swelling of polyacrylamide hydrogels

this work provides guidelines for understanding and predicting the hydrolysis-induced swelling behavior of paam hydrogels under alkaline conditions, and is important for their utilization. polyacrylamide (paam) hydrogels are widely used and studied. their feature of hydrolysis is often ignored. when paam hydrogels are stored under alkaline

water treatment polyacrylamide polymer science wiley online library

abstract. polyacrylamide (pam) and its derivatives are the most commonly used polymers in the preparation of polymeric gels for water control in petroleum reservoirs. this study involved the use of polyethylenimine (pei) as a crosslinker for pam. in this study, we investigated pam alkaline hydrolysis at high temperatures.

insights into the application of new eco-friendly drilling.based on their results, the mpp enhanced mud rheological properties and minimized the seepage loss, suggesting that mpp can be an efficient drilling fluid additive. potato peels powder (ppp) is another example of food waste additive addressed by al-hameedi et al. (2019c). their outcomes exhibited that the ppp had no effect on mud weight, but

investigation of the degradation and stability of acrylamide

muller et al. [31], proposed that polyacrylamide would hydrolyze under slightly acidic conditions (ph 4), and reported that the molecular weight of the polymer remained relatively stable during hydrolysis. thomas et al. [32], investigated the effects of different ph conditions and reaction times on the hydrolysis process. results indicate
