Fabricating an anionic polyacrylamide (APAM) with an anionic

2.1. Materials The monomer AM and SAS were purchased from Chongqing Lanjie Tap Water Company (Chongqing, China). Urea [CO (NH2)2] and initiator 2,2′-azobis [2- (2-imidazolin-2-yl)propane]dihydrochloride (VA-044) were sourced from Apotheker Chemical Reagent Co., Ltd. (Chendou, China).

anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template. The chemical properties of the polymers were observed by Fourier transform infrared spectroscopy (FT-IR), scanning

Jun 1, 2017 · Abstract. Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template

Oct 1, 2020 · The application of synthetic polymers such as anionic polyacrylamides (APAM) in enhanced oil recovery (EOR) may increase in the future. This can lead to environmental release through offshore produced water discharges with so far limited knowledge on impacts in marine ecosystems. We investigated impacts of APAM polymers on two marine copepod

May 30, 2017 · anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium

Anionic polyacrylamide APAM - Water Treatment Chemicals

Anionic polyacrylamide APAM is a polyacrylamide with electronegativity, and its functional group is sulfonic acid, phosphoric acid and carboxylic acid. In the process of wastewater treatment, flocculation is regarded as an important purification technology.

ANIONIC POLYACRYLAMIDE | ATP Chemicals

Anionic Polyacrylamide is the most efficient and popular chemicals flocculant used for wastewater processing. - Using ACCOFLOC E 2341 in retention system (Compozil) will reinforce retention, drainage, durability of wet paper. - Anionic Polyacrylamide can cause skin and eye irritation.

ANIONIC POLYACRYLAMIDE | Ataman Kimya A.?.

It is known as the most widely used additive. Anionic polyacrylamide is the generic name for a group of very high molecular weight macromolecules produced by the free-radical polymerization of acrylamide and an anionically charged comonomer, mainly the sodium salt of acrylic acid, sodium acrylate.

Anionic/Cationic PAM|Polyacrylamide Polymer

APAM Aniocic polyacrylamide Introduction: Anionic polymer flocculant is mainly used for the treatment of solid minerals in the neutral suspension. Anionic polyacrylamide is used to improve the removal effect of the suspended solids, COD and phosphate in the urban and industrial wastewater treatment.
