- •
Synthesis of Ni–Cr–CO3 LDH, RGO–Ni–Cr–CO3 LDH, Ni–Cr–DBS LDH and Ni–Cr–LA LDH.
- •
Organic Ni–Cr LDH shows larger sorption amount for high concentration MO.
- •
Large specific area of RGO–Ni–Cr–CO3 LDH and the bridge of RGO and MO in the presence of heavy metals may enhance sorption.
- •
MO sorption is on the external surface of organic Ni–Cr LDH and affected by the partition into the interlay organic phase formed by organic anions.
