In Situ Forming MnFe2O4/D201 Magnetic Composite Adsorbents for High Selectivity Adsorption and Deep Treatment of As(V) from Wastewater
A new magnetic adsorbent, namely, MnFe2O4/D201, with deep-treatment ability and high selectivity adsorption for As(V) was prepared. According to isotherm adsorption and kinetics, As(V) adsorption is primarily used for chemical bonding throughout the single-layer adsorbing process. The maximum As(V)...

| description | A new magnetic adsorbent, namely, MnFe2O4/D201, with deep-treatment ability and high selectivity adsorption for As(V) was prepared. According to isotherm adsorption and kinetics, As(V) adsorption is primarily used for chemical bonding throughout the single-layer adsorbing process. The maximum As(V) adsorption capacity of MnFe2O4/D201 can reach 35.8 mg/g at pH 3. MnFe2O4/D201 also exhibits higher selectivity adsorption against Cl-, NO3-, SO42-, and PO43-. According to the thermodynamic results, the adsorption process was spontaneous and endothermic. The adsorption capacity is maintained at 81% of the initial after ten adsorption-desorption cycles. As(V) concentrations ranging from 1 mg/L to 10 μg/L can be treated in fixed-bed column experiments. The effectual cure volume of As(V) reaches 1332 BV (26.64 L). The removal mechanism primarily comprises electrostatic attraction and complexation. |
