Research on a new cationic polyacrylamide (CPAM) with a cationic

The cationic monomers on these microblock segments can be polymerized to form a CPAMD with a new cationic microblock structure. In addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (Wiesbrock et al. 2004; Hoogenboom and Schubert 2007

Transfer and degradation of polyacrylamide-based flocculants in

The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems. Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain

Cationic polyacrylamide copolymers (PAMs): environmental half life

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.
