摘要
为建立一种高灵敏度、高选择性的水合肼检测方法,采用电沉积方法在FTO基底上制备3,4,9,10-苝四酰二亚胺(PTCDI)薄膜,用XRD,FT-IR,UV-vis,SEM等仪器对其进行表征,并采用电化学工作站测量该薄膜对水合肼的传感性能。结果表明,水合肼浓度1~150μmol/L范围内灵敏度为0.153μA·μmol^(-1)·L·cm^(-2),在150~1000μmol/L浓度范围内灵敏度为0.212μA·μmol^(-1)·L·cm^(-2),检出限为161.9 nmol/L,该薄膜对水合肼具有良好的电化学传感性能。
Characterized by XRD,FT-IR,UV-vis and SEM,3,4,9,10-perylenetetraimide(PTCDI)films were prepared on FTO substrates by electrodeposition to establish a highly sensitive and selective method for the detection of hydrazine hydrate.The sensing performance of the films for hydrazine hydrate was measured by an electrochemical workstation.The results showed that the sensitivity of the film was 0.153μA·μmol^(-1)·L·cm^(-2) in the concentration range of 1~150μmol/L and 0.212μA·μmol^(-1)·L·cm^(-2) in the concentration range of 150~1000μmol/L.The detection limit was 161.9 nmol/L.The film has good electrochemical sensing performance for hydrazine hydrate.
