Water Soluble Polymer Flocculants: Synthesis, Characterization,

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Cationic polyacrylamide copolymers (PAMs): environmental half life

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C

Recent Achievements in Polymer Bio-Based Flocculants for Water

Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)¡ªa non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8,9,10]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80]. Both

Chen et al. [14] prepared a cationic, hydrophobically modified, multilayered sheet PAM (CPAC), through ultraviolet (UV) short-wave-initiated polymerisation and treated metal processing wastewater. The introduction of hydrophobic monomers enhanced the interaction between CPAC and the particles, and cationic monomers increased the electrostatic attraction between them, enabling the effective
