研究目的
To develop a metal-organic framework thin-film coated optical fiber sensor for detecting specific organic contaminants in water, utilizing Fabry–Perot Interferometry and fast Fourier transform analysis.
研究成果
The UiO-66 MOF thin-film coated optical fiber sensor effectively detected rhodamine-B and methyl viologen in water, demonstrating physical and chemical interactions through FFT analysis. The sensor's performance indicates potential for water quality monitoring, though technical limitations need addressing for broader application.
研究不足
Sensor detection threshold, water temperature variations, and barometric pressure fluctuations.
