- •
Single phase MgAl and MgFe LDHs were synthesized from calcined dolomite.
- •
Calcined dolomite was utilized as Mg source as well as precipitant.
- •
Sorption density of arsenate was reflected by the exchange capacity of LDHs.
- •
Highest sorption density and coverage of arsenate was found with Mg2.3Al-LDH.
- •
Inner surface complexation happens in sorption of arsenate on Mg4Fe-LDH.
