Best Practices Guidance for the Use of Anionic Polyacrylamide

Common uses of PAM as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds wastewater and drinking water treatment clarification of effluents in industries like pulp & paper, aquaculture Also popular for erosion prevention in irrigation furrows and on construction sites. Fish have a negative charge on their gill mucous.

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

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

investigation of adsorption mechanism of phosphate (v) ions

Investigation of adsorption mechanism of phosphate (V) ions

The sorption properties of Na-A-type synthetic zeolite, obtained from fly ash with regard to the phosphate(V) ions, were determined. The Na-A zeolite was prepared using hydrothermal conversion of fly ash with aqueous sodium hydroxide. The effects of solution pH and zeolite surface modification by ionic polyacrylamide (PAM) were examined. Both anionic and cationic forms of PAM were applied. The
