摘要
酚类化合物广泛应用于各行各业,但它们是一类毒性大的化合物,即使在极低浓度下也会对人类、动物和环境造成很大的危害,因此检测痕量的酚类污染物至关重要.在众多酚类化合物的检测方法中,成本低、效果好、易操作的电化学方法脱颖而出,但裸电极并很难达到痕量检测的要求.金属有机骨架化合物(metal-organic frameworks, MOFs)材料是一种比表面积大、孔隙度高、结构多变,在多个领域表现优异的新型材料,以MOFs及其复合物或衍生物修饰裸电极是一种有效提高其检测性能的方法.本文对基于MOFs及MOFs复合物或衍生物表面修饰的电化学传感器在酚类污染物检测中的应用进行综述,总结MOFs基材料制备方法对其检测性能的影响,并展望其未来发展的趋势.
Phenolic compounds are widely used in all walks of life. They are highly toxic pollutants that can cause great harm to human beings, animals and the environment even at very low concentrations. Therefore, trace detection of phenolic pollutants is very important. Among many methods for the detection of phenolic compounds, the electrochemical method with low cost, good effect and easy operation stands out, but bare electrodes cannot meet the requirements of trace detection. Metal-Organic Frameworks(MOFs) are new materials with large specific surface area,high porosity and variable structure, and have been shown excellent performance in many fields.Modification of bare electrodes with MOFs and their composites or derivatives is an effective method to improve their detection performance. In this paper, the application of surface-modified electrochemical sensors based on pristine MOFs, MOFs composites and MOFs derivatives for phenolic pollutants detection was reviewed. The influence of preparation methods of MOFs-based materials on the detection effect was summarized, and the trend of this type of sensors for phenolic detection in the future was prospected.
