Cationic starch-grafted-cationic polyacrylamide based
The total monomer concentration (m/m%) is the percentage of all monomers in the total mass of the reaction mixture, where m AM: m CS: m DMDAAC is 6: 4: 3.The effect of total monomer concentration on positive charge density, intrinsic viscosity, GR and GE of CS-g-CPAM was investigated at initiator dosage of 0.2%, post-polymerization temperature of 55 °C, and post-polymerization time of 24 h.
Recently, more attentions have been paid to natural polymer-based flocculants in water treatment, since they are believed to be low-cost, nontoxic, and environmentally friendly materials. In this work, strong cationic chitosan-based graft copolymer flocculants (3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CTA) modified chitosan-graft-polyacrylamide, denoted as chitosan-CTA-g-PAM) have
Cationic Polyacrylamide "Water-in-Water Emulsion
The concept,preparation,application and advantages over powdered and gelled polymers are presented for "water-in-water emulsion" of cationic polyacrylamide CPAM in an introductory part.The preparation of a 20% "W/W emulsion" of CPAM is described by copolymerizing acrylamide and methacrylamidoxyethyl trimethyl ammonium chloride in aqueous solution at the presence of a stabilizer and an
Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or

- What is poly aluminum chloride (PAC) in water treatment?
- In the realm of water treatment, various chemicals play a crucial role in ensuring the provision of clean and safe water. One such chemical is Poly Aluminum Chloride, commonly known as PAC. In this blog post, we will introduce what PAC is, its properties, applications, and its significance in water treatment processes.
- What is poly aluminum chloride (PAC)?
- Poly Aluminum Chloride (PAC) plays a significant role in water treatment by effectively removing impurities, clarifying water, and improving its overall quality. Its high coagulation efficiency, broad applicability, and low dosage requirements make it a valuable asset in the pursuit of clean and safe water.
- Is polyaluminum chloride used in water treatment?
- Polyaluminum chloride (PAC) can be synthesized and used in water treatment as investigated in this study using a colorimetric speciation method. Stable preparations of PAC solutions can be produced where a relatively stable cationic polymer predominates.
- What is a preformed polyaluminum salt?
- Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
