Abstract A facile and highly sensitive electrochemical sensor for salidroside was fabricated based on multilayer ultrathin films (UTFs) containing Ni–Al layered double hydroxide (LDH) and carbon fibers that obtained by electrospinning technology. The X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) images show that the film surface is synthesized successfully. In addition, we constructed the electrochemical sensor using the composite nanomaterials we prepared to achieve detection of salidroside and this sensor showed a good linear range (0.2–120 μM) and a low detection limit (0.067 μM). It has also been successfully applied to the detection of actual samples, compared with HPLC method, satisfactory recovery rates have also been obtained.

镍铝水滑石纳米片包覆碳纳米纤维的制备及其在红景天苷检测中的应用

摘要 基于含有镍铝层状双氢氧化物 (LDH) 的多层超薄膜 (UTFs) 和通过静电纺丝技术获得的碳纤维，制备了一种简便且高灵敏度的红景天苷电化学传感器。X射线衍射（XRD）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）图像表明薄膜表面合成成功。此外，我们使用制备的复合纳米材料构建了电化学传感器以实现红景天苷的检测，该传感器显示出良好的线性范围（0.2-120 μM）和低检测限（0.067 μM）。也已成功应用于实际样品的检测，与HPLC法相比，也获得了满意的回收率。
