Oscillation-Based Fluorescence Real-Time Spectroscopy for Determination of Formaldehyde in Textiles
In this study, we present an innovative method for real-time monitoring and determination of formaldehyde (HCHO) in textiles using oscillation-based fluorescence spectroscopy (OBFS). This method utilizes a high-sensitivity fluorescent dye that exhibits strong fluorescence when exposed to HCHO. The OBFS system consists of a light source that emits laser light pulses at regular intervals, which synchronize with the oscillation pattern of the sample container. When the laser pulse hits the sample container, it excites the fluorescence dye molecules in the container, causing them to emit light. By measuring the intensity of the emitted light and analyzing its temporal and spectral characteristics, we can determine the amount of HCHO present in the textiles. Our experimental results demonstrate that the proposed method is highly accurate and reliable, with sensitivity comparable to traditional methods such as gas chromatography and flame ionization detector. This technique has potential applications in various industries where formaldehyde emissions are regulated, including textile manufacturing, air conditioning systems, and medical devices.
在纺织品中，甲醛被广泛用作防皱、防霉和防虫的化学处理剂，过量的甲醛可能会对人体健康产生不良影响，特别是对于哮喘和其他呼吸道疾病的患者，准确测量纺织品中的甲醛含量至关重要，近年来，振荡式荧光实时光谱(OSFS)法作为一种非破坏性测试方法，已经在纺织品甲醛检测领域取得了显著的应用。
OSFS是一种利用纺织品表面含有的颜料与甲醛反应产生的荧光信号来定量分析甲醛浓度的方法，该方法具有响应速度快、准确性高的优点，同时避免了样品的破坏，因此越来越受到业界的欢迎。
OSFS的基本原理是，当纺织品暴露在甲醛中时，甲醛会与纺织品表面的颜料分子发生反应，形成一种稳定的化合物，这种化合物能吸收特定波长的紫外线(UV),然后发出荧光，通过测量这个荧光信号的强度和持续时间，可以计算出甲醛的浓度。
为了提高检测的准确性和灵敏度，OSFS需要对振荡条件进行精确控制，这包括振荡时间、振荡频率、光源强度和光谱范围等因素，振荡时间的选择会影响到颜料与甲醛的反应速度；振荡频率则会影响到荧光信号的稳定性；光源强度则会影响到荧光信号的强度；光谱范围则会影响到能够检测到的甲醛浓度范围。
OSFS还需要考虑其他因素，如样品的前处理过程、环境温度和湿度等，因为这些因素都可能影响到荧光信号的强度和稳定性，为了保证OSFS方法的准确性和可靠性，需要对这些因素进行适当的控制和管理。
振荡式荧光实时光谱(OSFS)法是一种有效的纺织品甲醛检测方法，通过精确控制振荡条件和考虑其他影响因素，可以提高检测的准确性和灵敏度，随着科学技术的不断发展和进步，我们期待OSFS方法在未来能更好地服务于纺织品安全检测领域。
这只是一个大概的文章框架，具体内容需要根据实际研究需求进行深入扩展和阐述。
