control of the colloidal depletion force in nonionic polymer solutions by complexation with anionic surfactants

Control of the colloidal depletion force in nonionic polymer solutions by complexation with anionic surfactants

Hypothesis Charge, size and concentration of depletants control the magnitude and range of depletion and structural forces. Noncovalent association of nonionic polymers with ionic surfactants may therefore synergistically enhance these forces to an extent that depends on the structure and composition of the resulting complexes.

improving flocculation performance of copper flotation tailings by conventional and new technology polymers - water, air, & soil pollution

Improving Flocculation Performance of Copper Flotation Tailings by Conventional and New Technology Polymers - Water, Air, & Soil Pollution

The flocculation of copper tailings was carried out using the novel UMA Magnafloc 5250 (anionic) and traditional polymers based on polyacrylamide (anionic Magnofloc 155 and 336, nonionic 351, and cationic SPP 355) at polymer dosages ranging from 5 to 80 g/t.

Interactions between cellulose nanocrystals and anionic and neutral polymers in aqueous solutions | Cellulose

Physical structures of aqueous cellulose nanocrystal (CNC) suspensions in anionic polyelectrolyte carboxymethyl cellulose (CMC) and non-ionic poly (ethylene oxide) (PEO) were investigated by studying their cross polarized, polarized optical microscope (POM) images and dynamic light scattering, zeta potential, 1 H spin–lattice relaxation nuclear ...

surfactant self-assembling and critical micelle concentration: one approach fits all? | langmuir - acs publications

Surfactant Self-Assembling and Critical Micelle Concentration: One Approach Fits All? | Langmuir - ACS Publications

Critical micelle concentration (CMC) is the main chemical–physical parameter to be determined for pure surfactants for their characterization in terms of surface activity and self-assembled aggregation. The CMC values can be calculated from different techniques (e.g., tensiometry, conductivity, fluorescence spectroscopy), able to follow the variation of a physical property with surfactant ...

Polymers | Free Full-Text | Surfactant-Modulation of the Cationic-Polymer-Induced Aggregation of Anionic Particulate Dispersions

Commodity formulations contain many chemically distinct components and their mutual interactions define the beneficial characteristics of the formulation. Mixing oppositely charged polymers and surfactants invariably induces macroscopic phase separation, to a degree dependent on the prevailing polymer and surface charge densities, and the interaction can be modulated by added ionic surfactants ...

Optimization and economic evaluation of modified coagulation - SpringerOpen

The imposed cost for treating one cubic meter of ceramic-tile wastewater treatment by PAC + anionic and PAC + anionic and non-ionic polymers in comparison with PAC alone was reduced to 22.96% and therefore economically more affordable for the tile industry wastewater treatment. Introduction

65 Chapter 3 UNCHARGED OR NON-IONIC POLYMERS 3.1. INTRODUCTION Among the wide variety of uncharged, linear polymers which are commercially available or can be synthesised in the laboratory, only the watersoluble varieties have, for obvious reasons, been extensively studied as complex formers with clays. Such polymers invariably possess numerous ...
