The invention discloses a ratio type fluorescence detection method for rapidly detecting trace water in an organic solvent. The method comprises the following steps: (1) preparing a pyrene derivative fluorescence sensor storage solution; (2) preparing a standard solution; and (3) drawing a standard curve to obtain various linear equations. The fluorescent sensor for detecting the trace water in the organic solvent is a pyrene derivative, the preparation process is simple, and meanwhile the process for detecting the trace water in the organic solvent has the advantages of being easy to operate, extremely fast in response, high in sensitivity, good in selectivity and low in cost. 本发明公开了一种快速检测有机溶剂中微量水的比率型的荧光检测方法：(1)芘衍生物荧光传感器储存液的制备；(2)标准溶液的配制；(3)标准曲线的绘制得到各类线性方程为。本发明用于检测有机溶剂中微量水的荧光传感器为芘类衍生物，制备过程简单，同时检测有机溶剂中微量水的过程有操作简单、响应极快、灵敏度高、选择性好、成本低的优点。
