摘要:

为检测食品变质过程中产生的乙二胺气体,采用Alder法合成了四苯基卟啉和四苯基卟啉铁化合物,通过核磁(1H NMR)、场发射扫描电子显微镜(FE-SEM)、红外光谱(IR)、紫外可见光谱(UV-Vis)等手段对其进行表征,并以四苯基卟啉铁作为敏感试剂,利用旋涂法制备了四苯基卟啉铁薄膜/K+交换玻璃光波导传感元件,对多种气体进行检测。 结果表明:该传感元件对乙二胺气体具有较好的选择性响应,较高的灵敏度,在1×10-10~1×10-4(V/V0;V:被检测气体体积,V0:空气体积)体积比范围内,体积比与输出光强度间线性关系良好(R=0.9940),响应时间和恢复时间分别为3 s和11 s,信噪比S/N=4.8,RSD=0.5%(V/V0= 1×10-7)。 平行试验中,其结果也具有良好的线性关系(R=0.9985),证明该传感元件对乙二胺气体检测的准确性。 该类传感元件在食品品质检测方面有很好的应用与发展。

Abstract:

To detect ethylenediamine gas produced by the degradation of flavor during food deterioration process, tetraphenylporphyrin iron was synthesized via Alder method and its thin film/K+ exchanged glass waveguide sensor were prepared by spin coating. This sensor exhibits selective and high sensitive response to ethylenediamine. In the volume ratio range of 1×10-10~1×10-4(V/V0), there is a good linear relationship between the volume ratio and output light intensity(R=0.9940). The response time and recovery time are 3 s and 11 s, respectively. The signal to noise ratio(S/N) is 4.8, RSD=0.5%(V/V0=1×10-7). Good linear relationship between the volume ratio and output light intensity(R=0.9985) in parallel experiments also proves the accuracy of this sensor toward ethylenediamine gas detection. This sensor has potential application in the field of food quality examination.
