Synthesis of bimetallic organic framework material M/Fe-MOF (M: Ni, Cu, Mn) and testing to remove toxic dyes in water environment

In this study, the combination of Fe(III) and Ni(II), Cu(II), or Mn(II) metal salts bound to organic bridges were synthesized based on thermal method solvent in the presence of DMF. The structural properties of the materials were analyzed based on modern physicochemical methods (XRD, FT-IR, SEM, and BET). | Chuyên san Phát triển Khoa học và Công nghệ số 8 4 2022 Synthesis of bimetallic organic framework material M Fe-MOF M Ni Cu Mn and testing to remove toxic dyes in water environment Thi Kim Ngan Tran1 2 Cao Phuong Khanh Phan3 Thi Cam Quyen Ngo1 2 Ngoc Bich Hoang1 2 Le Dang Truong1 2 Thi Kim Oanh Nguyen1 2 1 Institute of Applied Technology and Sustainable Development Nguyen Tat Thanh University Ho Chi Minh City 700000 Vietnam 2 Faculty of Food and Environmental Engineering Nguyen Tat Thanh University Ho Chi Minh City 700000 Vietnam 3 Faculty of Chemical Engineering Ho Chi Minh City University of Technology Ho Chi Minh City Vietnam Corresponding author nganttk@ ARTICLE INFO ABSTRACT The treatment and removal of toxic dyes in the aquatic environment are considered an urgent issue today. In addition to the development of traditional materials a new material a bimetallic organic framework has received the attention of many researchers because of its outstanding properties and potential in high porosity and high porosity applications. surface rich in functional groups. On the basis of the above practices Fe-MOF-based metallic materials modified with Ni Cu and Mn were synthesized by the solvothermal method. Evaluation of the materials from XRD SEM FT-IR diffraction measurements and BET surface area measurements. From there draw conclusions and evaluate the possibility of successful synthesis in the fabrication of new MOF materials. The adsorption capacity of the materials was preliminarily evaluated through the adsorption process of organic dyes. The results of structural characterization showed that the modification with metal ions did not change the original crystal structure of the material as well as the partial replacement of the second metal ion in the Keywords lattice node. The material after a modification has a large bimetallic organic framework specific surface charge and at the same time increases the ability .
