Temperature influence of nonionic polyethylene oxide and anionic polyacrylamide on flocculation and dewatering behavior of

Nonionic polyethylene oxide (PEO) and anionic polyacrylamide (PAM) flocculation of kaolinite dispersions has been investigated at pH 7.5 in the temperature range 20¨C60 C. The surface chemistry (zeta potential), particle interactions (shear yield stress), and dewatering behavior were also examined.

Evaluation a self-assembled anionic polyacrylamide flocculant for the treatment of hematite wastewater: Role of microblock structure

Anionic polyacrylamide (APAM) as an important flocculant possess the advantages of high molecular weight, acceptable flocculation performance, low cost and green [4]. The anionic chemical groups in APAM are able to neutralize the positive charge of colloid particles in the wastewater and lead them to crash, aggregate and settle.

Anionic polyacrylamide efficiency in goethite removal from aqueous solutions: goethite suspension destabilization by PAM - International Journal

The main aim of the study was to investigate the anionic polyacrylamide (PAM) efficiency as a flocculant relative to goethite particles. This mineral is a toxic waste produced during hydrometallurgical processes and, as a result, poses a threat to the environment. In the experiments, the following analytical methods were applied: potentiometric titration, zeta potential and adsorption amount

Transfer and degradation of polyacrylamide-based flocculants in hydrosystems: a review | Environmental Science and Pollution Research

Anionic PAMs used in flocculation applications are water soluble and have little if any cross-linking. The molecules, when dissolved in water, are nominally linear, although they may be coiled or curled to varying degrees due to either substitution along the chain or as a result of electrolytes in the solvating water (Sojka et al. 2007 ).

The stability mechanism and thermal properties of the system alumina¨Canionic polyacrylamide (PAM) was studied. The polymer¡¯s adsorption properties in dependence on the following parameters solution pH (in the range 3¨C9), temperature (in the range 15¨C35 ¡ãC), and carboxyl groups¡¯ content in the PAM chains (in the range 5¨C30 %) were examined.
