Ternary magnetic polymer cross-coupled in [γ-APTES]-dispersion to remove azole compound: economic research and educational policy management

The imbalance between economy and environment has been threatening the sustainable development goals of developing countries. Conservation of biodiversity and national sustainable development, and management of natural resources are also included in this study. The discharge of 1,2-aminoazophenylene (1,2-AAP), considered an emerging organic compound, into municipal wastewaters has caused hazardous environmental. We developed an easily recoverable nanohybrid [γ-APTES]-Fe3O4@PAN@AC (AFPA) through an in situ two-step process via co-precipitation of Fe3O4@PAN magnetic polymer. Then, Fe3O4@PAN particulates were cross-coupled with activated carbon in the [γ-APTES] solution. The maximum monolayer adsorption capacity (Qmax = 303.2 mg g−1) occurred at pH 7, 50 °C, and an equilibrium time of 6 h. Additionally, the desorption of 1,2-AAP from AFPA was examined to enumerate the critical reusability of the sample. Following investigation of the adsorption equilibrium under various conditions, we have suggested several plausible interaction mechanisms, included ion exchange, hydrogen bonding, hydrophobicity, dipole force, electrostatic interaction, and π-bonding. The newly determined adjacent distance of 0.32 nm was well associated with the (220) parallel plane of the Fe3O4@PAN interlayer distance, which encouraged the chemisorption of 1,2-AAP.
