Best Practices Guidance for the Use of Anionic Polyacrylamide

PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. The process is known as polymer bridging. One of the most common polymer flocculants on the market. Common uses of PAM as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds.

comparison of adsorption affinity of anionic and cationic

Comparison of adsorption affinity of anionic and cationic

In the case of anionic polyacrylamide, the adsorbed amount decreases with the increasing pH. The pK a value of anionic PAM is equal to 3.2 and in the studied pH range the degree of carboxyl groups dissociation is from 98.7 to 99.8%. Therefore smaller adsorption of AN PAM at pH 7 is caused by unfavorable electrostatic repulsion between the

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

The negatively charged, or anionic, PAMs, are much less toxic to aquatic organisms and are widely used in furrow irrigation agriculture. This type of PAM is the focus of this discussion, and all references to ¡°PAM¡± are to the anionic forms. PAM is available as a crystalline powder , an emulsion, or a solid block or ¡°log.¡± It is nontoxic

2. Type of Polyacrylamide 2.1. Anionic PAM Anionic PAM was a kind of water-soluble polymer which was prepared by anionic monomer and acrylamide monomer, or obtained by hydrolysis of PAM. There were both amide group and anion group with negative charge on the long chain of the polymer, such as maleic anhydride, acrylic acid and its sodium salt.

Polyacrylamide (PAM) and its copolymers with anionic and cationic monomers are important and widely used polyelectrolytes in industrial processes such as in waste water treatment as flocculent7,8, which can lower the charge of particles and make them settle. The charge of particles in natural suspensions is almost always negative;
