Abstract EN

A more applicable adsorbent was fabricated using industrial wastes such as red mud, fly ash, and riverbed sediments.

The heavy metal inside the raw materials created metal hydroxy on the adsorbent surface that offered elevated adsorption capacity for phosphorus.

The required equilibrium time for the adsorption is only 10 min.

The theoretical maximum adsorption capacity of the adsorbent was 9.84 mg·g−1 inferred from the Langmuir adsorption isotherm.

Higher solution pH favored phosphorus adsorption.

Kinetics study showed that the adsorption could be better fitted by the pseudo-second-order kinetic model.

The presence of coexisting anions had no significant adverse impact on phosphorus removal.

The speciation of the adsorbed phosphorus indicated that the adsorption to iron and aluminum is the dominating adsorption mechanism.

Moreover, a dynamic adsorption column experiment showed that, under a hydraulic time of 10 min, more than 80% of the phosphorus in the influent was removed and the surplus phosphorus concentration was close to 0.1 mg L−1.

The water quality after adsorption revealed its applicability in real treatment.

Consequently, the adsorbent synthesized from industrial wastes is efficient and applicable due to the high efficiency of phosphorus removal and eco-friendly behavior in solutions.
