  • 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.
  • Is Apam a uniform polymer?
  • The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
  • 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.
  • Does microblock structure enhance reactivity and copolymerization of Apam-T?
  • Anionic polyacrylamide with regular microblock structure was synthesized. The reactivity and copolymerization degree were enhanced by microblock structure. The turbidity removal of APAM-T for hematite wastewater could reach 98.22 %. The charge neutralization and bridging adsorption capacity of APAM-T were enhanced.
