- •
Modifier affected the morphology, crystallinity, thermostability, acid–base property.
- •
The maximum Cu(II)/Cr(VI) adsorption capacity reached 50.14 and 38.82 mg g−1.
- •
The modification enhanced the selective Cr(VI) adsorption in binary metals system.
- •
Materials possess well reusability and adsorption performance in presence of anion.
- •
Metals adsorbed on Schwertmannite through surface complexation and anion-exchange.
