Water Soluble Polymer Flocculants: Synthesis

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

the preparation and ageing of acrylamide/acrylate copolymer

The preparation and ageing of acrylamide/acrylate copolymer

For powder-based products, the initial wetting, swelling and dispersion of the solid polymer is influenced by the powder size, such that activity may be extremely poor even after several hours. Emulsion-based flocculants effectively eliminate this stage, but both forms of the high molecular weight flocculants require at least an additional 24 h

Transfer and degradation of polyacrylamide-based flocculants

The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems. Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain
