polyacrylamide degradation and its implications in environmental

Polyacrylamide degradation and its implications in environmental

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which

ANIONIC POLYACRYLAMIDE - Santos

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

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

Water Soluble Polymer Flocculants: Synthesis, Characterization, and

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

Cationic polyacrylamides, ammonium-based polymers, poly (allyldimethyl-ammonium chloride) and epichlorohydrin/dimethylamine-based polymers are the most common CPEs used as coagulation and flocculation agents because they are economical and water soluble with tunable charge densities at high molecular weights.

Studies on flocculation characteristics of chromite¡¯s ore process

Batch sedimentation studies were carried out to measure the settling rate of chromite ore tailings using anionic, cationic and non-ionic polyacrylamide flocculants (Alstafloc 40, 60, 107, 155,155X, 155XX and 50) of different ionicity and molecular mass. All batch sedimentation experiments were carried out at 5% (w/w) solid concentration.

Polymeric flocculants are typically classified based on their ionic character: non-ionic, cationic, anionic and amphoteric. 2 Commercial flocculants are often based on polyacrylamide (PAM) and its derivatives since acrylamide (AM) is one of the most reactive monomers to undergo radical polymerization, thus allowing ultra-high molecular weight polymers to be built easily. 5 In addition, AM is
