Application
Poly(acrylamide-co-acrylic acid) and its sodium salts (APAM) are widely used as thickening agent, binder, super absorbent, soil conditioner, filtering aid, flocculating agent, crosslinker, suspending agent, lubricant, and oil recovery agent. One of its largest uses is waste water treatment. When added to waste water, it causes suspended particles to aggregate and to precipitate. In municipal and industrial waste water treatment it can be used in all liquid-solid separation processes including primary sewage treatment. PAMs are also used to treat water from mineral mining operations. Another common use is oil extraction and recovery. When water is injected into the well, PAM assists in pushing oil locked in reservoirs towards the pump by increasing the viscosity of the injected water.
Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering. The primary use is waste water treatment. As a primary organic coagulant, it neutralizes negatively charged colloidal particles and thus induces flocculation and sedimentation which reduces sludge volume. In paper mills, it is mainly used to enhance retention and dewatering.
Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation. When an electic field is applied across a PAM gel, the (negatively) charged proteins or nucleic acids migrate across the gel away towards the positive electrode. Since the mobility depends on the charge and size of the molecules, each molecule species migrates differently through the gel matrix.
