This study utilizes the synthesis of three different metal oxides: Fe3O4, Co3O4, and NiO, to enhance the removal efficiency of tetrahydrofuran (THF) by adjusting the ratio of metal oxide incorporated into sodium alginate films. In the initial experiments, the three types of particles were synthesized and characterized. The particles were then incorporated into sodium alginate films, and the characteristics and hydrophilicity of the films were analyzed. Next, permeation evaporation experiments were conducted using 90 wt% THF as an organic dye. The experiment was first carried out with varying time durations, and it was found that 6 hours was the most stable time. Thus, 6 hours was selected as the control time for subsequent experiments. The films with different metal oxides incorporated were then tested for permeation evaporation, and the THF removal efficiencies were compared to determine which had the best performance. Among the different compositions, the Alg/1% Co3O4 film showed the best performance, achieving a purity of 99.965% water. The Alg/NiO film also showed a gradual improvement in performance.
