Polyelectrolyte polymers—Types, forms, and function

Polyelectrolytes are macromolecules that, when dissolved in a polar solvent like water, have a (large) number of charged groups covalently linked to them. In general, polyelectrolytes may have various kinds of such groups. Homogeneous polyelectrolytes have only one kind of charged group, e. g. only carboxylate groups.

To get good results in drinking water treatment, where polyelectrolytes must be avoided for their mutagenic property, low aluminium-content and high basicity PAC 9%-10% Al 2 O 3 is employed. Usually, PAC 9%-10% Al 2 O 3 is produced by simple dilution of PAC 18% Al 2 O 3, adding a basifier like Na 2 CO 3, in order to reach a final basicity of 58

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
