UiO-66材料在环境中去除污染物的研究现状及发展前景

Research Status and Development Prospects of UiO-66 in the Removal of Pollutants in the Environment

本文对国内现阶段环境污染情况和工业污染物治理问题的简要分析发现,吸附治理方法拥有操作简便、不产生二次污染物、高效去除污染物等优势,更优于其他方法。然而国内现阶段广泛应用于工业污染物治理的传统吸附剂的吸附能力低、稳定性差,导致治理成本高。因此,开发一款选择性吸附能力强、稳定性好、可重复利用的吸附剂,有利于降低工业污染物吸附治理成本。研究发现,金属有机碳框架材料——UiO-66稳定性佳、结构可塑性好,且具有高比表面积和孔隙率等优点,是作为吸附剂的良好选择。未来有希望在实际工业污染物治理中逐步替代低效吸附剂,减少污染物的排放,降低治理成本。

In this paper, a brief analysis of the current domestic environmental pollution situation and industrial pollutant treatment problems found that the adsorption treatment method has the advantages of simple operation, no secondary pollutants, and efficient removal of pollutants, which is better than other methods.However, the traditional adsorbents widely used in the treatment of industrial pollutants have low adsorption capacity and poor stability, resulting in high treatment costs. Therefore, the development of an adsorbent with strong selective adsorption capacity, good stability and reusability is conducive to reducing the cost of adsorption and treatment of industrial pollutants. The study found that the metal organic carbon framework material-UiO-66 has good stability, good structural plasticity, and has the advantages of high specific surface area and porosity, which is a good choice as an adsorbent. In the future, it is hoped that inefficient adsorbents will be gradually replaced in the actual industrial pollutant treatment, so as to reduce the emission of pollutants and reduce the cost of treatment.
