Polyacrylamide degradation and its implications in

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which...

Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)¡ªa non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8,9,10]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

Transfer and degradation of polyacrylamide-based flocculants

Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.

However, excessive flocculant dosage (> 40 mg/L) would result in the sludge particle surface coverage by superfluous polymer chains. At this time, there are fewer exposed active sites conducive to adsorption and bridging, thus leading to poor flocculation effect (Wan et al. 2007 ; Zhang 2017 ).

Therefore, it is difficult to clarify naturally. Now, factories still use the high polymer flocculant to deal with coal slurry wastewater in general. However, the use of high polymer flocculant is not only expensive, but also can produce secondary pollution [75,76]. It is very important to find a kind of economic and safe flocculant to deal ...

The impact of polyacrylamide flocculant solution age on

The dissolution of the powdered polyacrylamide flocculant was found to be a slow process. The dosages required to achieve measurable flocculation decreased as the flocculant age was increased up to 72 h, reflecting the release of discrete polymer chains from highly agglomerated solution species.
