Evaluation of sand-clay-anionic polyacrylamide blends for alternative

2.2 Anionic polyacrylamide (APAM) Polyacrylamide (PAM) is a non-ionic super-absorbent polymer composed of a large chain of monomers obtained from the polymerization of acrylamide (Barvenik 1994 [14]). They have an important capacity for water absorption and retention, and they can act as a hydrogel (Mechtcherine 2015 [28]). In the presence of ionic
