ANIONIC POLYACRYLAMIDE - Santos

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.

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

Improving Flocculation Performance of Copper Flotation

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. Jar tests were carried out with suspensions prepared at 10% (w/w) solids concentration.

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C
