Intrinsic viscosity is independent of concentration (c) by virtue of extrapolation of reduced viscosity to c=o. The intrinsic viscosity of polymer is related to its relative molecular weight and its existing form of molecular chain, which is

High quality Dewatering Primary Sludge Cationic Flocculant Polyacrylamide High Efficient and Low dosage from Cooking, Cooking's leading water soluble polymer product, with strict quality control industrial water treatment chemicals factories,
The viscosity of polyacrylamide solution is related to its molecular weight and formulation concentration. 4, polyacrylamide dissolved: dissolved in order to play a full play flocculation. Sometimes need to speed up the dissolution rate, then
Properties of Polyacrylamides
Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation. When an electic field is applied across a PAM gel, the (negatively) charged proteins or nucleic acids migrate
Flocculation is an efficient and cost-effective method for water and wastewater treatment. The main type of polymeric flocculant is polyacrylamide and its derivatives [1–3], however, hydrophobically associating polyacrylamides (HMPAM) flocculant
Polyacrylamide degradation and its implications in environmental systems | npj Clean Water
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity
Anionic polyacrylamide has no potential to bioaccumulate, being completely soluble in water (solubility is only limited by viscosity) and insoluble in octanol. Additionally, being a flocculent, it adsorbs onto suspended matter and, in this way,
Synthesis of a Cationic Polyacrylamide under UV Initiation and Its Flocculation in Estrone Removal - Hindawi
A ternary cationic polyacrylamide (CPAM) with the hydrophobic characteristic was prepared through ultraviolet- (UV-) initiated polymerization technique for the estrone (E1) environmental estrogen separation and removal. The monomers of

Loss of solution viscosity in water of increasing ionic strength is a major problem encountered in the use of the partially hydrolyzed polyacrylamide polymers for improved oil recovery. It is recognized widely that the viscosity loss is more
- Does polyacrylamide functionalize Fe 3 O 4 nanoparticles?
- The polyacrylamide functionalized Fe 3 O 4 nanoparticles produced showed resistance to leaching in an acidic medium due to protection by the carbon layer. The ability of the Fe 3 O 4 nanoparticles to adsorb heavy metals was improved through functionalization with a polyacrylamide layer.
- What is the purpose of carbon coating?
- Carbon coating was applied to protect magnetic nanoparticles within an acidic medium and the carbon layer was also utilized for adsorptive removal of heavy metals. Additionally, a protective coating layer was implemented together with attaching some functional groups to improve their adsorption efficiency [ 28 ].
- What is copper-catalyzed controlled polymerization of acrylamide?
- Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
