Applicazioni

Poly(acrylic acid, sodium salt) solution has been used to study the mechanism of formation of supramolecularaggregates of polyacrylic acid(PAA) in the presence of Fe(lll). This supramolecular association traps all Fe(lll) and prevents the precipitation of Fe (OH)3.The chelation capacity of PAA can be exploited to inhibit the precipitation ofhematite and other iron oxides.

Itcan be used as a draw solute in forward osmosis process due to its flexibilityin structural configuration and high solubility in water. They can be preferredover conventional ionic salts as they can produce comparable water flux andmuch lower reverse leakages.

It can also be used to study the effect of the molecular weight of PAAon crystal nucleation and the growth of CaCO3 during thecrystallization process.
