采用荧光光谱法对咪唑啉类缓蚀剂的残留浓度进行检测。咪唑啉类抑制剂在445 nm激发波长处发出较弱的荧光，曙红Y的加入使荧光强度明显增强，激发波长位于521 nm处。荧光强度与抑制剂浓度呈良好的线性关系。基于荧光光谱法，以曙红Y为荧光剂，油田采出水中常见离子不影响咪唑啉的检测。
Fluorescence spectroscopy is applied to detect the residual concentration of imidazoline inhibitors in this study. Imidazoline inhibitors emit a weak fluorescence spectrum at 445 nm excitation wavelength, the addition of eosin Y can enhance the fluorescence intensity obviously and the excitation wavelength is located at 521 nm. The fluorescence intensity has a good linear relationship with the inhibitor concentration. The common ions in oilfield production water do not affect imidazoline detection using eosin Y as fluorescence agent based on fluorescence spectroscopy.
