It is an urgent topic for public health and environmental protection to remove Cr(VI) from wastewater effectively conveniently. Herein, we fabricate the novel hybrid magnetic material HPU-13@Fe3O4 (HPU-13 = {[Cu3(L)2]·OH·2CH3CH2OH·10H2O}n; HL 2-(5-pyridin-4-yl-2H-[1,2,4]triazol-3-yl)pyrimidine), which shows excellent removal efficiency easily employed as a reusable absorbent. The maximum capacities of Cr2O72– CrO42– adsorbed on were 398.41 471.69 mg/g, respectively, larger than those reported MOFs used in adsorption. Adsorption mechanism studies confirmed that synergistic reaction reduction adsorption was responsible high efficiency. above evidence proved has potential functional ability decontaminate polluted water systems.
