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

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide (APAM) is a kind of polyacrylamide (PAM) and shows electronegative which contains functional groups of sulfonic acid, phosphoric acid or carboxylic acid . Due to more charge, the molecular chain of polymer can be more stretching in the water which will increase the capacity of adsorption and bridge for suspended particles ...

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]

Water Soluble Polymer Flocculants: Synthesis

They are used to flocculate positively charged particles in many industrial units, such as municipal wastewaters and sludge dewatering. 34 Acrylic acid (AA) is a commonly used anionic monomer, and anionic derivatives of polyacrylamide can also be obtained by post-polymerization hydrolysis with an alkali such as NaOH to create carboxyl groups on ...

Cationic polyacrylamide copolymers (PAMs): environmental half

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

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 - an overview | ScienceDirect Topics

Anionic PAM usually contains about 5% polyacrylic acid groups formed by copolymerization of acrylamide and acrylic acid monomers or by hydrolysis of PAM homopolymer under conditions to convert some of the amide groups to carboxylate salts. PAM with as much as 50% acrylic acid is used.
