- •
The morphological and mineralogical properties of dolomite–palygorskite clay were characterized.
- •
Batch experiments were performed for the removal of Cu(II).
- •
The removal efficiency and capacity of Cu(II) by dolomite–palygorskite clay were superior to common dolomite and palygorskite.
- •
Precipitation on the mineral-water interfaces was the main removal mechanism.
- •
The submicron dolomite with nanopores enhanced the removal of Cu(II).
