Polyacrylamide
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
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 modifier and friction

Polyacrylamide hydrazide suitable for immobilization
Polyacrylamide hydrazide; Cells are suspended in a solution of linear, water-soluble polymer, which is then gelled by addition of a suitable cross-linking agent (e.g., glyoxal).

Application of the Margin of Exposure (MoE) approach
Acrylamide (CH 2 CHCONH 2, CAS Registry No. 79-06-1) is an industrial chemical used since the 1950s as a chemical intermediate in the production of polyacrylamides, which are used as flocculants for clarifying drinking-water and other industrial applications.The neurotoxicity of acrylamide in humans is well known from occupational and accidental exposures.
Sodium acrylate is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) when intended for use in or on food it is of appropriate food grade and
- Can polyacrylamide based flocculants be used in wastewater treatment?
- The existing polyacrylamide-based flocculants are widely used in the treatment of wastewaters with various compositions (Al-Karawi et al., 2011; Lin et al., 2017). The Saratov Chemical Plant of Acrylic Polymers Akripol currently develops and introduces new polyacrylamide-based modifications of flocculants into industry.
- How can polyacrylamide and inorganic flocculants improve water quality?
- Improve water quality. In drinking water treatment and industrial wastewater treatment, the combined use of polyacrylamide and inorganic flocculants can significantly improve water quality. Improve the strength and settling speed of flocs.
- What are the different types of polyacrylamide water treatment?
- Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.
- Which flocculants are used in wastewater treatment?
- Summary of chitosan, cellulose, and alginate-based flocculants used in the treatment of wastewater TOC, total organic carbon; CNC, cellulose nanocrystal. Stimuli-responsive polymers are a class of macromolecules that undergo conformational changes and switch their solubility when the right stimulus is applied.
