Synthesis and application of amphoteric polyacrylamide
The synthetic method of amphoteric polyacrylamide is studied. The effects of reaction temperature, reaction concentration and reaction time are discussed in details. In the flocculation tests , the flocculant behaviors of inorganic polymer coagulant and the composites of inorganic polymer coagulant and organic polymer coagulant are studied respectively.
Through two‐phase aqueous polymerization, amphoteric polyacrylamide (AmPAM) emulsion, as an environmental friendly flocculant for the tannery wastewater, was firstly synthesized using ammonium sulfate aqueous solution as the dispersion, using acrylamide, cationic monomer ethylene methyl propenoyl‐trimethylammonium chloride (DMC), and anionic monomer acrylic acid (AA).

- What is nonionic polyacrylamide (NPAM)?
- Nonionic polyacrylamide (NPAM) is a type of high molecular polymer or polyelectrolyte. Its molecular chain contains nonionic polar groups that can adsorb suspended solid particles in water and bridge them to form a large flocculate.
- Can powder polyacrylamide flocculants be fed to sewage?
- Powder polyacrylamide flocculants couldn’t be directly feed to the sewage. It is necessary to dissolve it in water first and then use its water solution to treat the sewage. The water to dissolve the granular polymer should be clean (such as tap water), rather than sewage. The water at the normal temperature is workable, no need to be heated.
- Can polyacrylamide gel electrophoresis standardize venom protein analysis?
- This comparative study evaluates various protein quantitation assays, including those using polyacrylamide gel electrophoresis, to standardize venom protein analysis from different Hymenoptera species, aiding in venom research and potential therapeutic applications (Wanandy et al., 2025).
- How do you prepare a sinofloc nonionic Pam solution?
- The solutions of SINOFLOC nonionic PAM must be prepared in suitable plants equipped with dry powders feeding and dispersion units and with continuous and moderate agitation.
