  • What is polyacrylamide used for?
  • 1. Introduction Polyacrylamide (PAM) is widely used in various industries, such as wastewater treatment; oil-displacing; paper making; textile printing and dyeing; dredging; and cosmetics . It is mainly polymerized by acrylamide (AM) and the molecular weight can reach 1.5 million to 20 million.
  • How is textile industry wastewater treated?
  • The treatment of this effluent is highly essential before its discharge into the water bodies as it can contaminate the aquatic habitats and can cause harm to aquatic life. Treatment of textile industry wastewater is carried out using physical processes, chemical processes and advanced oxidation processes (AOP).
  • What is the purity of polyacrylamide (PAM)?
  • The polyacrylamide (PAM) was obtained from Sigma-Aldrich, with purity > 99%. The Direct Blue 78 (DB78) with the commercial name Tubantin GLL 300 has a molecular weight of 1059.95 g/mol and a maximum wavelength (λ max) of 604 nm. It is soluble up to 10 g/L at 25 °C and is commonly used in the textile industry.
  • How is textile dyeing wastewater treated?
  • In one such study, treatment of textile dyeing wastewater was done with the EC process using TiO 2 /Zn-TiO 2 /Zn electrodes by spray pyrolysis of TiCl 3. Spacing between electrodes was kept at 1 cm, electrode dimension 9 cm × 3.3 cm × 0.5 cm, total effective electrode area 28.16 cm 2. The process was conducted after adjusting current and pH.
