Efficient Absorption of Antibiotic from Aqueous Solutions over MnO₂@SA/Mn Beads and Their In Situ Regeneration by Heterogeneous Fenton-Like Reaction

Figure 6

Pseudo-first-order (a) and pseudo-second-order (b) adsorption kinetics for adsorption of NOR onto MnO₂@SA/Mn at different initial NOR concentrations at reaction conditions: [catalyst] = 2.0 g·L⁻¹, [H₂O₂] = 2 mM, pH = 4, = 30°C.
