The role of cationic polyacrylamide in the reverse flotation of diasporic bauxite - ScienceDirect
Cationic polyacrylamides, of molecular weight ∼1.1 × 10 7, were provided by Polyacrylamide Engineering and Technology Center of Guangzhou, Cooking. The cationicities of DA-1, DA-3 and DA-5 CPAM were 12%, 25% and 36%, respectively.
The pK b value for the cationic polyacrylamide is 9.3. At pH 5 and 7 the degree of quaternary amine groups dissociation in the polymer chains varies in the range of 99.4–99.9%. Thus, all cationic groups of the polymer are present in the ionized

Flow properties of cellulose fiber suspensions flocculated by cationic polyacrylamide | Semantic Scholar
Abstract Retention aid systems are commonly used in the papermaking process to flocculate the fine matericals in cellulose fiber suspensions. The addition of polymeric flocculants such as cationic polyacrylamide (C-PAM) also increases the fiber
Cationic surfactants. Cationic surfactants are less common in cleaners, and almost always absent from carpet products. Cationics have positively charged ends, which makes them ideal in antistatic formulas like fabric softeners and automobile

Cationic polymer, hydroxy aluminum, and clay minerals are three flocculants with different action mechanisms and a more cost-efficient multiple flocculant can be prepared by compositing them through appropriate technology. All of attapulgite
- Can polyelectrolyte be used as a coagulant aid?
- If polyelectrolyte is used as a coagulant aid low dosage of polyelectrolyte is required. So, this fact ruled out the possibility of toxicity in the treated water. more toxic (Goodrich et al., 1991). polyelectrolytes in treated water is an important factor. water (Ghimire and Bhattarai, 2025).

- Can cationic polyelectrolytes remove nom from water?
- Another very important potential application is the removal of NOM from water, which can be achieved by cationic polyelectrolytes. In natural waters, most organic matter is in the form of humic substances, which are essentially natural anionic polyelectrolytes covering a range of MW and of rather complex structure.
- Does microblock CPAM improve dewatering properties?
- Compared to random copolymers, the microblock, cationic structures improved dewatering properties because of their increased charge neutralization and bridging properties. 94, 95 Li et al. 93 also studied microblock CPAM structures in flocculating sludge water. Figure 5 depicts sludge water before and after treatment with CPAM. 93
