Influence of molar mass of partially hydrolyzed
Flocculants are used to treat the produced water, and this work proposed to evaluate the EOR produced water treatment and the impact of the EOR polymers molar masses on the oil removal efficiency. For that, partially hydrolyzed polyacrylamide (HPAM) with different molar masses were used as the EOR polymer, while the flocculant used was a
1. Introduction. The leather industry is an important economic sector in many developing countries, having Brazil the biggest cattle herd in the world (ABQTIC, 2025).However, it can be a source of environmental pollution due to the discharge of potentially toxic and hazardous polluted wastewater into the environment if not properly treated for decontamination (de Souza et al., 2016; Yadav et
Potential Use of Polyacrylamide for Soil Erosion Control
Potential Use of Polyacrylamide for Soil Erosion Control in Brazil Article (PDF Available) in Journal of Sustainable Development 3(4) · November 2010 with 224 Reads How we measure 'reads'
High-molecular-weight, anionic polyacrylamide (PAM) is added to irrigation water to reduce soil erosion during furrow irrigation of crops. The chemical nature of PAM, together with the observation that the polymer can be biotransformed by soil bacteria, led us to question the impact of PAM treatment on the fate of coapplied agrochemicals.
The Impact of Coronavirus in Brazil: Uneven Prospects
COVID-19’s impact on the beauty and personal care industry will mostly present two distinct scenarios. In the personal care space, sales should not present a negative performance. In fact, sales of categories such as bath and shower are expected to grow in the short term, with many consumers looking for items such as bar and liquid soaps.

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- 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.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- How cationic polyacrylamide (PAMC) is prepared?
- Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
- How do cations affect the hydrolysis of Pam/HPAM polymers?
- These cations not only can form complexes (gels or precipitates) with the carboxylic groups with HAPM to alter their rheological and phase properties, they can also catalyze the amide hydrolysis reaction to increase the degree of hydrolysis of PAM/HPAM polymers.
