Method for detecting content of polycaprolactone

The invention provides a polycaprolactone content detection method. The method comprises the following steps: determining a target characteristic absorption band of polycaprolactone; and determining the concentration of the polycaprolactone in the solution to be detected by using a standard curve method according to the absorption peak integral area under the target characteristic absorption band, so that the content of the polycaprolactone can be detected by the method, and the problems in the prior art are solved. 本申请提供聚己内酯含量检测方法。该方法包括：确定聚己内酯的目标特征吸收带；利用所述目标特征吸收带下的吸收峰积分面积，使用标准曲线法确定待测溶液中聚己内酯的浓度，因此通过该方法能够检测聚己内酯的含量，从而解决了现有技术中的问题。
