纤维素材料在非金属阴离子传感领域的研究进展

Research progress of cellulose materials in non-metallic anion sensing field

阴离子是生物体和自然界中常见的物质,在发挥重要作用的同时也可能带来一些不利影响。因此,针对各种非金属阴离子的传感得到了大量研究,而作为传感器支撑材料的纤维素因其优异的性能以及低成本备受关注。针对几种典型的非金属阴离子(F^(-)、Cl^(-)、ClO^(-)、CN^(-)、NO_(3)^(-)、NO_(2)^(-))所开发的纤维素基传感器进行了详细的总结,对比了不同类型传感器之间的原理以及性能,并分析了其在比色、荧光和电化学等各类传感技术中的重要作用。最后,对纤维素基非金属阴离子传感所面临的挑战进行探讨,并展望了其未来的发展前景。

Anions are common substances in living organisms and nature,which play important roles but may also bring some adverse effects.Therefore,a large amount of research has been conducted on the sensing of various non-metallic anions,and cellulose,as a supporting material for sensors,has attracted much attention due to its excellent performance and low cost.A detailed summary of cellulose-based sensors developed for several typical non-metallic anions(F^(-),Cl^(-),ClO^(-),CN^(-),NO_(3)^(-),NO_(2)^(-))was conducted.The principles and performance of different types of sensors were compared,and their important roles in various sensing technologies such as colorimetry,fluorescence and electrochemistry were analyzed.Finally,the article explored the challenges faced by cellulose-based non-metallic anion sensing and looked forward to its future development prospects.
