Abstract

Disclosed is a method for preparing an acid-resistant Zr-metal-organic framework (Zr-MOF) material with selective adsorption of hexavalent chromium, which is specifically a method for preparing a MOF material with selective adsorption of hexavalent chromium. The present invention aims to solve the technical problems that the existing MOFs have poor water stability, is unstable in an aqueous solution, and therefore may structurally collapse. In addition, the micropore characteristics of most MOFs have affected the mass transfer rate of the adsorbate, which in turn limits the industrial application thereof. The MOF of the present invention has excellent water stability and acid resistance, showing a strong adaptability and great potential in treating mostly acidic industrial wastewater. As a new functional material for water treatment, the MOF has optimal selective adsorption capacity and a desirable adsorption capacity for hexavalent chromium in water, which improves the recycling and later resource utilization.
