摘要

在电池石墨电极（BGE）上的多壁碳纳米管（MWCNTs）的电位窗口 - 1 至 1.5 V 内，以 100 mV s-1 的扫描速率循环 10 次，使用循环伏安法对马尿酸（HA）进行电聚合的新型改性传感器。聚（HA）/MWCNT/BGE 传感器的线性范围分别为 3.00 × 10-3 至 1.00 µM（5.29 × 10-4 - 0.18 µg/ml）和 5.00 至 1.00 × 103 µM（0.88- 176.22 µg/ml），检测限（LOD）为 0.06 × 10-2 µM（1.06 × 10-4 µg/ml），定量限（LOQ）为 2.00 × 10-3 µM（3.52 × 10-4 µg/ml）。聚（HA）/MWCNTs/BGE 传感器成功地应用于色氨酸和人体血清中 SER 的测定，回收率范围为 98.31-105.47%，RSD 值为 3.02-4.77%。采用绿色化学指标：国家环境指数（NEMI）、分析绿色度量（AGREE）、Raynie 和 Driver、绿色分析程序指数（GAPI）以及分析生态尺度，结果表明所提出的传感器可归类为优秀的绿色方法，分析生态尺度得分为 84 分。

Application of recycled battery graphite decorated with poly hippuric acid/ multiwalled carbon nanotubes as an ecofriendly sensor for serotonin.

A novel modified sensor based on electropolymerization of hippuric acid (HA) using cyclic voltammetry within the potential window - 1 to 1.5 V for 10 cycles at a scan rate 100 mV s^-1 over multiwalled carbon nanotubes (MWCNTs) on battery graphite electrode (BGE). Poly (HA)/MWCNTs/BGE sensor exhibited two linearity ranges 3.00 × 10^-3 to 1.00 µM (5.29 × 10^-4 - 0.18 µg/ml) and 5.00 to 1.00 × 10³ µM (0.88- 176.22 µg/ml) with limit of detection (LOD) of 0.06 × 10^-2 µM (1.06 × 10^-4 µg/ml) and limit of quantification (LOQ) of 2.00 × 10^-3 µM (3.52 × 10^-4 µg/ml). The poly (HA)/MWCNTs/BGE sensor was successfully applied to the determination of SER in the presence of tryptophan and in human blood serum with recovery ranges 98.31-105.47% with RSD values 3.02- 4.77%. Green chemistry metrics : national environmental index (NEMI), analytical greenness metric (AGREE), Raynie and Driver, green analytical procedure index (GAPI), and the analytical eco-scale were employed and indicated that the proposed sensor can be classified as an excellent green method, achieving an analytical eco-scale score of 84.
