摘要

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