Anionic polyacrylamide is a water-soluble synthetic polymer with negatively charged functional groups, widely used in industries and environmental applications. Its main role is as a flocculant and coagulant in water treatment processes, where it aids in the aggregation and settling of suspended particles, impurities, and solids, facilitating their removal and purification from water sources. Beyond water treatment, anionic polyacrylamide has applications in enhanced oil recovery in the petroleum industry, soil conditioning for agriculture, and enhancing particle retention and drainage in the paper and textile industries. Its versatility in improving solid-liquid separation and reducing environmental contamination makes it a critical component in various industrial and environmental processes.
