摘要: 建立了一种快照式成像光谱仪快速检测印染废水的方法。配制单一组分以及混合组分的模拟印染废水，优化了实验条件，以白光LED阵列光源为检测光源，用实验室研发的成像光谱仪采集样品的图像，获得样品400~800 nm范围的光谱信息，建立了样品吸光度与浓度的线性关系。单一组分的罗丹明B和橙黄G的线性范围为1~50 mg/L，线性相关系数均大于0.99，回收率为93%~114%，相对标准偏差（RSD）为7.5%和1.3%；利用多元线性回归模型对混合样品的检测，相关系数均为0.999，各组分的测量相对误差均有改善。实验结果表明，本方法具有快速、准确和重复性好等优点，可以作为印染废水现场检测和应急检测的方法。

Abstract: A rapid detection method for dyeing wastewater by snapshot imaging spectrometer was developed. The simulated dyeing wastewater solution of a single component and mixed components was prepared and the experimental conditions were optimized. The white LED array was used as the detection light source and the image of the sample was collected by the imaging spectrometer developed in the laboratory to obtain the spectral information of the sample in the range of 400-800 nm. The standard curve between the absorbance and the concentration of the samples was established. The linear range of a single component of Rhodamine B or Orange G was 1-50 mg/L, the linear correlation coefficients was more than 0.99, the recoveries were 93%-114% and the relative standard deviations (RSD) were 7.5% and 1.3%. The correlation coefficients between predicted concentration and reference concentration reached 0.999 in the detection of mixed component by using the multiple linear regression model, and the relative errors of 3 predicted samples were reduced. The rapid, accurate and precise method showed an excellent promise for on-site and emergency detection of dyeing wastewater.
