  • Is Apam-t a novel anionic polyacrylamide?
  • APAM-T is a novel anionic polyacrylamide which has been successfully synthesized by ultrasonic initiated template copolymerization. Characterization results showed the evidence of the microblock structure’s existence and the enhancement of copolymerization degree by adding the template.
  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • Does Apam-t improve flocculation performance in hematite wastewater treatment?
  • The flocculation performance was evaluated by the change in turbidity removal and zeta potential when treating hematite wastewater compared to the existing flocculants. The results indicated that APAM-T showed the best flocculation performance due to enhanced charge neutralization and bridging adsorption.
  • What is the atomic percentage of Apam?
  • And the atomic percentage values are listed in Table 3. Meanwhile, the theoretical molecular formation of APAM and APAM-T is (C 3 H 5 ON) 8 (C 3 H 5 SO 3 Na) 2, when the dosage of SAS in the total monomer is 20 %, O/C = 0.467, N/C and S/C = 0.667. It coincided with the result of XPS analysis approximately.
