| Abstract Scope |
Wastewater containing Cr(III) ions in hydrometallurgy is likely to cause harm to the surrounding environment and the human body. In this paper, Fe-MOF was synthesized by a solvothermal method and employed as an adsorbent to remove Cr(III) ions from hydrometallurgical wastewater. The effects of initial concentration and pH on the chemical forms of Cr(III) were mainly evaluated, while the influence of adsorption time and solution pH on the removal of Cr(III) ions under different initial concentration conditions were comprehensively analyzed. Under a contact time of 2 h, pH 7.0, and concentration of 100 mg·L-1, the optimum adsorption efficiency of Cr(III) ions was 82.63%. The adsorption methods of Cr(III) by Fe-MOF were investigated by batch adsorption experiments and kinetic simulations, and the results suggested that Fe-MOF has a promising application in the treatment of high-concentration Cr(III)-containing waste liquids. |
