利用发光二极管和氘灯光源的紫外吸收和阈值检测器对水中污染物进行了研究。测定了邻苯二甲酸氢钾、噻虫胺、色氨酸、噻虫嗪、尿酸和四聚乙醛在200-360 nm范围内的吸收光谱。只有四聚乙醛不适合在此范围内检测。对于其他污染物,以及成对化合物的混合物,透射信号可以近似地用源-吸收-检测器系统的简单光谱模型来描述。在两个波长上进行的综合测量可以确定某些混合物中的相对浓度,并在水槽中演示了实时吸收测量。
Contaminants in water were studied using ultraviolet absorption with light emitting diode and deuterium lamp sources, and a thresholding detector. The absorption spectra of potassium hydrogen pthalate, clothianidin, tryptophan, thiamethoxam, uric acid and metaldehyde were obtained in the range 200–360 nm. Only metaldehyde was not suitable for detection in this range. For the other contaminants, and mixtures of pairs of compounds, the transmitted signal could be approximately described with a simple spectral model of the source–absorption–detector system. Combined measurements at two wavelengths could allow relative concentrations in certain mixtures to be determined, and real-time absorption measurements were demonstrated in a flume.
