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

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

Preparation and properties of cationic polyacrylamide

SiO2 particles of different particle sizes were prepared by sol¨Cgel method using ethyl orthosilicate (TEOS) as raw material. Nano-silica/cationic polyacrylamide (S-CPAM) prepared by inverse emulsion polymerization of modified silica (C-SiO2) as a hydrophobic component with acrylamide (AM), dimethyl diallyl ammonium chloride (DMDAAC) and Methacryloyloxyethyl trimethyl ammonium chloride (DMC

The hydrophobically associating polyacrylamide with a cationic microblock structure denoted as TPADL was synthe-sized by UV-initiated template copolymerization of a cationic monomer (DAC), a hydrophobic monomer (LA) and acrylamide (AM). As can be imagined, both the cationic microblock struc-ture and the hydrophobic groups were incorporated into the

Additionally, it is of great significance to reduce the cost of subsequent treatment and prevent environmental pollution (Zhou et al., 2017; Wang et al., 2013). Among various chemical conditioners, cationic polyacrylamide (CPAM) is widely used in sludge treatment plants due to its advantages of fast treatment rate and wide application range.
