Solubility Study of Polyacrylamide in Polar Solvents - CORE
Abstract. Contact angles and surface tension data were measured to obtain the surface tension components of polyacrylamide (PAM). According to Van Oss, Chaudhury, and Good (VCG) theory, the surface tension components were used to calculate the PAM solubility in five different polar solvents: water, ethylene glycol (EG), acetone, ethanol, and dimethyl formamide (DMF).

The Solubility of Polyacrylonitrile
The comparative study of the thermodynamic solubility of PAN in five solvents led to the following conclusions: the thermodynamic solubility of PAN, characterized by the experimental and calculated cloud point curves, differ significantly for two kinds of solvents: organic aprotic and inorganic aqueous solution of NaSCN; the solubility of PAN in an aqueous solution of NaSCN is much higher than
The solubility of FTDO 46 in a series of polar and non-polar solvents was determined at ambient temperature (Table 6). 20 For solutions in DCM an increase in solubility was observed on addition of 2,4-dinitro-2,4-diazapentane (DNP) (solvotropic effect), attributed to the formation of a 1:1 molecular compound of 46 with DNP (see Section 4.1.2.2).
Predicting Cosolvency. 1. Solubility Ratio and Solute log
The solubility ratio of organic chemicals in an organic solvent and in water, σ, has been found to correlate with the logarithm of the octanol−water partition coefficient (log Kow) of the solutes; i.e., log σ = N + M log Kow. A total of 607 sets of thousands of solubility data were extracted from literature sources. From this database, values of N and M are obtained for 15 completely water
acuro manufactures high molecular weight anionic polyacrylamide powder (pam), which is effective in rapid precipitation of inorganic suspended solids in effluent water. anionic polyacrylamide is used in various industries like textile, sugar, mining, metal processing, electroplating, marble grinding & polishing, food processing and various other industries where water is used as a process medium.
Investigation of sludge conditioning performance
AbstractThe relation between the microstructure and sludge conditioning performance and mechanism of cationic polyacrylamide (CPAM) (low charge density (CD) CPAM C1, medium CD CPAM C4, and high CD CPAM C7) was extensively studied and recognized in this study. Igarashi and Pyun models based on reactivity ratio characterized the microstructure of the polymers.
Cationic polyacrylamide (CPAM) market revenue is forecast to grow at a CAGR of 7.2% from 2025 to 2027. This can be credited to the usage of cationic polyacrylamide as sludge conditioners, for its low dosage requirement, higher efficiency, and

- What is Pam used for in water treatment?
- PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
- Where is Pam used in water treatment & sludge dewatering?
- PAM used as a flocculant in water treatment or sludge dewatering is disposed in high-solid biogas digestors or landfills. 94 Although PAM is typically considered to be relatively recalcitrant to organic decomposition, 95 it can be degraded during anaerobic digestion.
- How do flocculants reduce water turbidity in coal slime water treatment?
- The flocculants, designed for coal slime water treatment, were characterized using the FTIR, XRD and SEM methods. It has been shown that water turbidity was reduced by ~97% and ~94%, while COD removal was ~78 and ~74% in the presence of Fe 3 O 4 -chitosan-cellulose and Fe 3 O 4 -chitosan-biochar, respectively.
- What is the mechanism of Pam-FECL 3 conditioning sludge flocculation?
- Mechanism of PAM-FeCl 3 conditioning sludge flocculation process. Based on the organic-inorganic hybrid mechanism mentioned in the previous section and the physicochemical characteristics of sludge dewatering, the synthesized hybrid flocculant could be regarded as a star hybrid ionomer reflecting Fe (OH)3 as a core and a PAM chain as an arm.
