Highly efficient removal of Malachite green from water by a magnetic reduced graphene oxide/zeolitic imidazolate framework self-assembled nanocomposite

- MRGO/ZIF nanocomposite was prepared via self-assembly and used for MG adsorption.
- MRGO/ZIF can exhibit an ultra-high adsorption capacity for MG of ∼3000 mg g−1.
- Adsorption isotherm was properly fitted to the Langmuir-Freundlich isotherm model.
- Effects of temperature, pH and co-existing compounds were investigated.
- Recyclability of MRGO/ZIF for MG adsorption was highly efficient and stable.
