摘要
试纸——通常指的是经过化学处理以后可对特定对象产生颜色变化的一类纸基产品,是人们进行快速检测分析的好帮手。本实验在玻璃纤维滤纸表面改性的基础上,设计了一种基于稀土配合物荧光传感特性的重金属离子检测试纸,充分展示了其在检测水中是否含有重金属离子方面的有效性与便捷性。创新设计的验“金”试纸在检测水源重金属离子污染方面大有用途,充分凸显了化学在促进生态文明建设方面大有可为。试纸的制作过程简单、安全与环保,所得验“金”试纸实用、易用与好用,实验过程既能科普试纸的一般制作与检验原理,又能激发学生进行科学探索与应用实践的兴趣,并在试纸使用的过程中传播生态文明的理念。本实验简单、易重复、门槛低、绿色环保且安全,实验过程具有独特的色彩美学,令人印象深刻,既适合在公众场所开展科普实验,又适合在小学高年级、中学和各本专科院校的实验教学中开展和普及。
Test paper,a type of paper product chemically treated to produce color changes in response to specific substances,serves as a valuable tool for rapid detection and analysis.This experiment,based on the surface modification of glass fiber filter paper,introduces a heavy metal ion detection test paper designed with the fluorescence sensing characteristics of rare earth complexes.The test paper demonstrates its effectiveness and convenience in detecting heavy metal ions in water sources.The innovative test paper proves highly useful in addressing heavy metal ion contamination in water,emphasizing the significant role of chemistry in advancing ecological civilization.The simplified,safe,and environmentally friendly process of creating the test paper yields a practical and user-friendly product.This experiment not only educates on the general production and testing principles of test papers but also sparks students’interest in scientific exploration and application.The experiment,characterized by its simplicity,repeatability,low entry barrier,environmental friendliness,and safety,possesses a unique color aesthetic,leaving a lasting impression.It is suitable for conducting popular science experiments in public places and promoting awareness in experimental teaching across various educational levels.
