How do you dissolve acrylamide?
Heat the 45% w/v solution to 37°C to dissolve the chemicals. Adjust the volume to 1 liter with distilled H2O. Filter the solution through a nitrocellulose filter (e.g., Nalge, 0.45-micron pore size), and store the filtered solution in dark bottles at room temperature.

What is acrylamide soluble?
WaterAcrylamide / Soluble inWater is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Wikipedia
Is polyacrylamide soluble?
Polyacrylamide is a water-soluble polymer that undergoes reactions typical of the amide group. The polymer in the solid state is brittle and not a good film former because of its relatively high glass transition temperature.
Is polyacrylamide water-soluble?
Polyacrylamide is a water-soluble polymer formed by the polymerization of acrylamide. It is a synthetic chemical that can be modified for usage in a broad range of applications. Polyacrylamide is commercially available in variants such as cationic, anionic, non-ionic, and others (including homopolymers and copolymers).
How do you make polyacrylamide solution?
Acrylamide Stock Solution Preparation and Recipe
- Prepare 800 mL of distilled water in a suitable container.
- Add 389.6 g of acrylamide to the solution.
- Add 10.4 g of bisacrylamide to the solution.
- Add distilled water until the volume is 1 L.
- Filter the stock solution using Whatman filter paper and store at 4°C.
How do you make polyacrylamide gel?
Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).
Is polyacrylamide soluble in water?
What are polyacrylamide used for?
Polyacrylamide (PAA) Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment.
Why is polyacrylamide used in water treatment?
Polyacrylamide is used to coagulate or flocculate solids in a liquid. This makes them useful in water treatment applications. Polyacrylamide increases the viscosity of water and is widely used in petroleum applications across the world to enhance oil recovery.
