摘要

由于氨是水溶性的,环境研究表明,肥料制造、食品、棕榈油、尿素肥料等工业废弃物如果管理不当,会对水体生态系统造成非常严重的破坏,导致水质下降。基于光学技术的器件,特别是结合光纤和纳米材料的器件,通过检测物理化学性质的变化,被认为对感兴趣的物种高度敏感。提出了一种实用、易用、价格低廉的氨浓度检测仪器,该仪器采用包覆二氧化钛掺杂卟啉的锥形光纤(TOF)。采用同时拉伸和加热的方法制备TOF。采用浸渍法制备了覆盖锥形光纤的tio2 /卟啉/明胶。扫描电镜分析表明,涂层的长度增加,直径减小,并且在锥度区成功地涂覆了二氧化钛和卟啉。EDX分析也证实了钛元素在TOF层中的存在。TOF对氨液浓度水平具有显著的传感性能。涂有二氧化钛结合卟啉的TOF可以在一定的输出电压范围内检测出每种浓度的氨浓度相差1 ppm。

Ammonia level sensor using tapered optical fiber coated with titanium dioxide-incorporated porphyrin
Since ammonia is water-soluble, environmental studies have shown that the industrial waste such as fertilizer manufacturing, food products, palm oil, urea fertilizer industry can cause very serious damage to water body ecosystems if not properly managed, resulting in a decrease in water quality. Devices based on optical technology, especially devices that combine optical fibers and nanomaterials, are identified as highly sensitive to the species of interest by detecting changes in physicochemical properties. A practical, easy-to-use, inexpensive instrument for detecting ammonia level was proposed using tapered optical fiber (TOF) coated with titanium dioxide-incorporated porphyrin. TOF was fabricated by simultaneously stretching and heating. The preparation of TiO 2 /porphyrin/gelatine was prepared to coat tapered optical fiber by dipping. SEM analysis shows an increase in length and a decrease in diameter, also the successful coating of titanium dioxide and porphyrin in the taper region. The EDX analysis also proves the presence of the Ti element in the TOF layer. The TOF produces significant sensing performances toward the ammonia liquid concentration level. The TOF coated with titanium dioxide-incorporated porphyrin can detect a one ppm difference in ammonia concentration with a certain range of output voltage for every concentration has.
