Synthesis and characterization of magnetic metal-organic framework (MOF) as a novel sorbent, and its optimization by experimental design methodology for determination of palladium in environmental samples

► A novel magnetic MOF for selective extraction of Pd (II) ions has been synthesized. ► The adsorption capacity of the method was calculated to be 105.1 mg g−1. ► Box-Behnken design was used to optimize the factors in adsorption and desorption steps. ► Box-Behnken design (BBD) is a fast, economical, and efficient way.
