  • What is cationic polyacrylamide?
  • Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
  • How is polyacrylamide gel prepared?
  • 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).
  • How to make polyacrylamide solution?
  • In a 50-ml glass bottle, mix acrylamide, H 2 O, TEMED, and 10% APS according to the recipe in Table 1 . Table 1. CAUTION: The linear polyacrylamide solution can be made as inert or activated with the capability of binding adhesive proteins.
  • What is polyacrylamide polymer gel treatment?
  • They include polymer flooding, alkaline-surfactant flooding, foam flooding, gel treatments, and so on. Among these methods, polyacrylamide polymer gel treatment is a common and cost-effective method because the process can reduce water cut by sealing the thief zone and redistributing the water drive.
