Polyacrylamide PAM Flocculant for Water Treatment – Chemate
Polyacrylamide PAM, with the chemical formula of (C3H5NO)n and the CAS NO. of 9003-05-8, is a linear polymer. Polyacrylamide polymer has good thermal stability, can be dissolved in water in any proportion, and the aqueous solution is a uniform
Synthesis of a cationic polyacrylamide by a photocatalytic surface-initiated method and evaluation of its flocculation and dewatering performance
The thermal stability (TG/DSC) of the polymers were determined by a TG/DSC/1100LF instrument (Mettler, G. C. Zhu, K. Fu and X. Fu, Synthesis of cationic polyacrylamide by low-pressure UV initiation for turbidity water flocculation, Chem.
Properties of Polyacrylamides
Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation. When an electic field is applied across a PAM gel, the (negatively) charged proteins or nucleic acids migrate

Stabilisation of β‐glucosidase entrapped in alginate and polyacrylamide gels towards thermal and proteolytic deactivation, Journal of Chemical
1/9/1998 · β‐D‐Glucosidase was immobilised by entrapment in two different matrices (calcium alginate and polyacrylamide gels), in order to compare how the immobilisation could stabilise the enzyme towards thermal and proteolytic deactivation. While the
Evaluation of phytotoxic effects of cationic polyacrylamide polymers: implication for the use of sludges as organic soil amendments in assisted
The effects of low charge density cationic polyacrylamide (CPAM) and high charge density cationic polydicyandiamide (PDCD) were investigated. Results demonstrated that CPAM was more effective than
A review of thermally stable gels for fluid diversion in petroleum production
1/5/2000 · Extensive studies in our laboratories (Moradi-Araghi et al., 1993), showed that the gels produced with thermally stable acylamide-based polymers dissolved in seawater and cross-linked with phenol and formaldehyde, are very stable.Fig. 2 shows a
