Difference and application of cationic, anionic and nonionic PAM

Cationic polyacrylamide (CPAM): is a linear polymer compound, because it is a water-soluble polymer, it is mainly used for flocculation, sedimentation and clarification of various industrial wastewater, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, sewage treatment, s...

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

1 BACKGROUND 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, Characterization,

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide, is highly water soluble, cost-effective, and very ...

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

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. [1] Physicochemical properties [ edit]

Polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). Due to the different nature of the groups present in the macromolecules, polyacrylamides can be divided into nonionic, anionic, and cationic ones.

Adsorption of Different Ionic Types of Polyacrylamide on

Specifically, it can be divided into non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), and cationic polyacrylamide (CPAM). C 3 H 7 ON, C 3 H 6 O 2 , and C 5 H 9 O 2 N + are the basic structural units of these PAM, resulting in different adsorption polarities [ 12 , 13 ].
