Adsorption of Different Ionic Types of Polyacrylamide on

The FTIR spectra and chemical structure comparison of the anionic, cationic and nonionic PAM used in the experiment are shown in Figure 16. From the graphs, it can be observed that all PAM formulations exhibit an absorption peak at 3338 cm ?1 , corresponding to the N-H stretching vibration of the amide groups in the acrylamide structure.

Optimizing the Flocculation Effect of Cationic Polyacrylamide

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were ...
