Construction of dual-imprinted UiO-66 s for highly efficient and synergistic Co-adsorption of diclofenac sodium and Cu(II)

•Cu(II) and DBA construct dual-imprinted pores in UiO-66 s to enhance the adsorption of Cu(II)/DCF.•Dual-imprinted UiO-66 s exhibit larger pores and expose more unsaturated Zr cluster/–OH.•DCF and Cu(II) were adsorbed by UiO(Zr/Cu)-DBA through H-bonding and coordination.•Adsorbed DCF/Cu(II) act as new bridging sites for UiO(Zr/Cu)-DBA to adsorb more Cu(II)/DCF.•UiO(Zr/Cu)-DBA shows high adsorption capacities for DCF/Cu(II) with 757/164 mg/g in binary system.
