Abstract Surfactant–polymer interactions were studied in the bulk solution using polyelectrolyte titration, nephelometric turbidity, dynamic light scattering and dynamic surface tension. For the preparation of complexes the surfactant quartolan (which is bearing a cationic charge), was used in combination with three polyanions that differ in their structure and molar mass. The interaction of

The surfactant concentration was kept constant while the polyanion concentration was varied. Different amounts of the polyanions (as 0.01 mol/l aqueous solution) were slowly added to the solution of the surfactant (0.005 mol/l) under stirring to obtain complexes with the charge ratio n−/n+ between 0 (pure surfactant) and 1.4 (polyanion in excess).

water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide

evaluation of anionic and cationic pulp-based flocculants

Evaluation of Anionic and Cationic Pulp-Based Flocculants

In wastewater treatment, flocculation is a widely used solid/liquid separation technique, which typically employs a charged polymer, a polyelectrolyte (PEL). Polyelectrolytes features, such as charge type, charge density and molecular weight, are essential parameters affecting the mechanism of flocculation and subsequent floc sedimentation. The effectiveness of the process is also influenced

ULTIMER Polymer Technology | Ecolab

ULTIMER technology is a breakthrough in polymer chemistry from Nalco Water. The basis for this breakthrough is the elimination of the hydrocarbon-based oils and surfactants required in standard latex polymer chemistry. ULTIMER chemistry is strictly water-based, yielding a much more stable, soluble, and user-friendly product.

Production and Application of Lignosulfonates and Sulfonated

Due to their unique properties, lignosulfonates have a wide range of uses, such as animal feed, pesticides, surfactants, additives in oil drilling, stabilizers in colloidal suspensions, and as plasticizers in concrete admixtures. 13, 14, 31-34 However, the majority of pulp mills employ kraft technology for pulp production, and thus, kraft lignin is more readily available for value-added

The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
